Been a while since I've been on here. Figured this was a cool little amp to share though. Picked it up yesterday so technically it's day after new amp day. It's a mid 70's Traynor YBA-4. Been looking for one for ages and was offered it as a trade for my Traynor studiomate. Was pretty much stock...

This one's kind of crude... kind of a rat rod of amps haha. I bought an old Bogen challenger PA a couple years ago and it kinda just got benched. I completely gutted it. It originally had a pair of 7868 power tubes, a 6c4 rectifier, a 6eu7 and 12ax7 in the pre amp. I put in a couple octal...

Been a couple years... Moved out to the east coast when covid first hit and I've been trying to sell my '76 VT-22 for over a year now with no interest. Even had the price down to $550 CAD. So I guess it's time to make a head box and turn this bad boy into a killer bass rig haha.

1969 Traynor YBA-1A Bass master mark II. Great condition for its age. All elecrolytics have been replaced. 3 prong power cord. Everything else is untouched. No mods. Original fan broke I have another fan wired in. Works great and sounds great. New tubes as well.

Hey guys. Been downsizing pretty big recently during covid. Not doing shows and all. I've started getting back into combo amps. I have a mid 70s Traynor YGM-4 that I'm using for guitar. For bass I have been using a 1969 Traynor YBA 1-A head and a 4x10. I want to get a combo of possible. Vintage...

Picked up a 1976 Traynor YGM-4 the other day. I picked it up for my guitar but when I heard it I had to try it on my bass. Two EL84s and 4 12ax7s. 4x8 speaker configuration. Bass and guitar both sound killer through this amp. Definitely happy with it!

Hey guys I'm changing out some old failing filter caps on this old Traynor amp and just had a quick question. The amp grounding is wired different then most of the Traynors I have seen. I'll attach a pic... the ground wires are connected from a node on the far side of the amp and go all the way...

I was bored and looking for something to do the last couple days... I recently picked up a Traynor YF-10 cab unloaded and I have a Peavey TNT150 combo that I love but it's way to Heavy. So i decided to merge the two. I turned the amp of the TNT150 into a standalone head and converted the YF-10...

Went to the local electronics store today and they did not have any Metal Heat Sink Power Resistors in the values I needed. I ordered some in but I also have a 90 watt tube amp I wanted to do some signal tracing on. I have a bunch of ceramic cement resistors in my stash is there anything I could...

Didnt really know where to put this.. I'm looking into getting my first oscilloscope and learning how to use it on repairs. I found a old HP 1707B online and it's the first one anywhere near me that seems to be in good shape. It's coming from a college grad that was taking electrical engineering...

Hey guys I'm working on a Bugera 6262 and it is driving me crazy. The issue is that intermittently the volume drops right out and then comes right back and it works fine again. Sometimes its within 15 mins of powering it up and other times I can play it for an hour or more with no issues. When...

So I just replaced several coupling caps on my one of my amps due to leaks and gave it a good inspection. When I powered it up it was louder than normal and only got worse when you played with any of the controls. After 2 days of swapping caps and trouble shooting I found a couple odd readings...

I was picking up parts at a electrical supply store today and I was talking to a tech about needing to replace a couple questionable coupling caps. The ones in there now are .022 uF 400V. He was showing me ones they had in the store that were .022 uF and 630V. Said that they would work fine. Is...

Recently just set up a new one. Waiting on my oscilloscope still but this will do for now.

Hey guys. I pulled a set of speakers out of a cabinet. The cab was rated at 8 ohm impedance and I was showing 8 ohms through my multimeter before I pulled the speakers. Once I got all the speakers out all four are testing at 22 ohms? Thoughts? Lol

Hey guys. After I picked up my YBA-1A it really peaked my interest into learning how tube amps work. I have been doing quite a bit of research on the components and how they all work. Safe practices... I'm now into the power section and signal path and trying to wrap my head around everything. I...

I recently just swapped out the pre amp tubes on one of my tube amps. Previously channel one was already super quiet but the 2nd channel that was voiced more for guitar/higher treble had a hum to it (fairly loud hum) but I figured that it was just due to the high treble. After the tube swap...

Recently picked up a Traynor bassmaster mark II and it currently has EL34 tubes in it. I know originally they came with 6CA7 tubes. I have never had a tube amp that has run either of these so I was just wondering the difference if any. Also with the old bassmasters I have read multiple articles...

Hey guys just a quick question. I own a couple tube amps which I bias and Change tubes on my own but they are newer amps and have test points and bias pots. I'm picking up an old YBA-1 Mark II tomorrow and I was just wondering the best way to check the Bias on it. It has been re cap'd and re...

I'm hopefully picking up an old Traynor YBA-1 mark ll tomorrow. It has been re tubed and caps were replaced. I just wanted to double check the speaker out. Does anyone know what its rated for? I have an 8 ohm cab that I wanted to use but I know some of the old Traynors were 4 / 2 ohms. Any of...

This DI box is brand new still in the box. Looking for 90$ OBO shipped (Canada/US lower 48). These are great DI box's and built to take a beating. I just don't need 2. ProDI - Radial Engineering

Just wondering if it is possible to have a amp modded to have a transformer balanced line out installed? I have a Traynor YBA200-2 which only has a pre or post EQ line out. Is this something that a amp builder or tech can do? Would love some feedback from some of the pros here. I attached the...

Pick up out of a 1978 stingray. Fully functional. Only issue is the wires from the pick up are pretty short now so it would be best to solder in a couple new ones. I was lazy and just soldered extensions on when I was using it lol. Will ship to Canada and lower 48 USA. Shipping included in price.

So i found a Bronco for dirt cheap online and just had to grab it for the price... and that I love SS basses now. Quick question though. Did they put out two different lines? I got the red version but it doesn't look like the newer ones online right now. The red is a nicer less toy looking red...

Been playing for over 20 years now. Never touched a short scale ever. Went out east this year and happened upon a Gretsch junior jet...... I am now selling off the couple longscales I have left. The bass I built I am converting to short scale. I'll keep one long just to have but wow I wish I...

Selling a case from a 1978 Music Man Stingray. Interior and latches in good condition. The outer Tolex is in fair condition for a 40 year old case. It has road rash but nothing significant. The case is still fully functional and all original. Asking $200 + Shipping (Canada and US lower 48). Will...

Does anyone know if they ever released any of the models to the public or was it just for him?

My band is currently in the process of finishing up material for an album. I wrote a lot of the material and most of it is in drop C#. I posted a while back while I was looking for a 2nd bass for alt tuning.. basically one I could just leave tuned half step down and I was kind of intrigued by...

Just finished up our yearly trip out east to Nova Scotia (25 hour drive!). Anyways while we were out there I popped into a Long & McQuade music store and they had a couple Gretsch G2220 Electromatic Junior Jet II's on display. I picked one up and fell in love with it. Nice warm bass and when...

Hey guys wondering about these Bronco bass's I keep hearing about. Theres's a lot of people on here that seem to love them. I normally only ever have one main bass I play out with but with the new album my band is working on I have been using some alternate tunings and would be nice to have a...

Price drop. 4 fully functional tuners off of a 1978 MM stingray bass. All mounting hardware included and in good condition.

I'm re tubing my amp today and while I was checking some stuff out I noticed my 4x10 cab which is rated at 8 ohms is reading about 6.2. I know some cabs are a little higher or lower than the rating but I've never had one with a 2 ohm difference. Should I be running my head in the 4 ohm or 8 ohm...

My Amp (Traynor YBA200-2) seems to be lacking a bit of power as of late. There has been no change in the quality of the sound just seems to be lacking some volume. I checked the bias of the power tubes and they are right in spec from when I checked them out a couple months ago. They are only 1...

So my bands in the process of writing songs for a new album. I have been heavily involved with the writing but it's been driving me nuts writing bass lines and waiting until we get to rehearsal to be able to get my guitar ideas to come alive. So for the first time in 20 years I bought a guitar...

*Posted this amp a couple months ago this is just a follow up* I switched to tube amps a couple years ago and never really looked back. Always felt I struggled to keep up power wise with my solid state stuff. I had 100,200,300,500 watt amps. All good quality... Ampeg, Hartke, Traynor, Ashdown...

Hey just wondering if anyone has the wiring diagram for the old 2 band EQ stingrays. The one I'm using was modified when I got it and was just wondering about the grounds because I am having battery drain issues.

Hey guys I recently did a custom build. I had ongoing neck issues with a '78 musicman Stingray so I Gutted it and fit it into the body of an old P bass I had. I love the results. It sounds exactly like the Ray still but the body is smaller/ lighter and the neck is much more comfortable as well...

Due to ongoing neck issues with my Old Stingray I made a big decision. I've come to love the sound of it and other bass's just don't compete with it. We had a big show coming up (last night) so I decided to Frankenstein my '78 Ray with one of my back up bass's, a mid 70's Northern Pbass. The...

So this should be interesting. Playing a Big charity event tomorrow night and the company providing the back line is one I've been feuding with the last couple years. I had bought a SVT CL off of them over two years ago and had nothing but problems with it. It fried while my band was on the road...

So I decided to change up my old Yamaha RBX. I took an old chrome humbucker that I had sitting in my parts bin forever now and routed/chiseled a spot for it closer to the bridge. Put new pots in it and made a custom pick guard. I will be getting a pick guard cut that exact shape but with out the...
