Genz Benz Streamliner, Part 10

#661
Try replacing tubes, one at a time, using a known good tube. Do so with the power turned off. If the new tube doesn't make a difference then out the original tube back in and Ho to the next one. It's almost certainly a tube. (Check the gain switch on the front too)

Agedhorse, what would the symptoms of a bad, intermittent, or weak connection from a fractured board be?

Can be a wide variety of symptoms, including ones that are the same as other unrelated causes. Generally, intermittent noises, loss of signal, distortions, pops, buzzes, etc. this is where good understanding of the products really helps in correctly diagnosing the real cause rather than an assumed but incorrect cause.

So, at what point is it better to try and diagnose it yourself rather than send it in to an expert such as yourself? I guess if the board is already damaged to the point it's showing symptoms then there's no harm done in swapping tubes to see if that's the problem.
That being said, are there any precautions that should be taken when swapping tubes to ensure there isn't any unnecessary board damage in the process?

Just be gentle. If its not a tube, I can take care if your problem at my R&D lab.

+1.
Much of the damage to circut boards are caused by people with "gorilla hands" and yanking them out and pushing them hard and fast into the socket.
I very gently and very slightly rock the tube while slowly pulling on it as I take one out. It is important to insure the pins on the tube you put in are not bent and you carefully line up the "Index" (on 12AX7 where the pin is missing) with the socket and gently and slightly rock the tube as you push it in place. DO NOT rock it too far as you will spread the socket pin tube connections and that will give you trouble on down the road.
It is not hard at all if you work slow and carefully.

Here is but just one place to get a 9 pin tube pin straightner.

Had to fiddle around with my SL-900 for about a month before learning how to properly EQ this baby. BASS AT 9 oclock,Mids at 2, treble at 10 = unlimited tone coupled with my old school Ampeg PR-410HLF. Everything else is obtained from my onboard controls. SATISFACTION!!:hyper:

Today I got a Hammond T-500 tonewheel organ moved into my living room. Just had to plug it into my Streamliner 600 and two Aguilar GS112s. Turning up the gain and flooring the swell pedal on the organ brought an instant Jon Lord-esque heavily overdriven tone :D absolutely yummy, but I had to turn down the bass quite a bit to tame the 50Hz hum from the organ.
A future plan is to get a Leslie 760 or similar and put the Streamliner preamp between the organ and Leslie for tone control and tube overdrive.

My rig has been getting hissy lately. I'm running a Stl900 into a gb focus 112 or a f 15/61. I don't use any attenuation on the tweeters and the hiss is noticeable between songs. I'm sure it's not my basses or effects as the noise is still there regardless of which basses I use and even when I run direct into the amp. Could it be the head? Maybe time for a tube change?

Single coil pups?
Click to expand...

Two of my basses have single coil pups and my lakie has bartolini mk1s which I think are humbuckers.

The rig used to be pretty silent, then I started to notice the hiss. I thought it might be dirty power, but the noise is still there regardless of where I plug in (rehearsal spaces or at home). The hiss is there when I've muted my tuner (inline between bass and amp).

Could be a tube then...

3 or 4 times in the last 4 years of ownership of my Shuttle 9 I've had some crackle and hiss. The problem with mine is the contacts on the valve base and the plugin valve bass holder become oxidized giving a bad connection. re seating the valve and valvebase holder and also spraying with servisol super 10 gets rid of the problem for x months.

I've owned two 5501's with MK1's. Both of them had quite noisy pickups when played in several venues. Great bass with the only weakness being the p/ups and electronics. I don't know, they may be 'buckers but they sure are not very quiet. YMMV hiss could be a tube on the way out.

I just want to try to settle all the rumors.. Its Official.. Jeff Genzler has left the building..
He is not with Fender any longer. Sad that Fender didnt use his talent to boost their bass amp line..
I hope he and crew come out with a new line in the future.. Just wanted everyone to know..
