Come on friends... I am looking for a schematic for my Little Mark 800. Mark Bass will only give schematics to "Authorized" repair facilities. Any suggestions?

Markbass Schematics

I just e-mailed the US Service manager for Mark Bass.. Funny, it is a Guitar Center address. Anyway, I will see what they say, but it is not looking good.
Nope. They are exchanged under warranty due to the wonderful warranty deal that MB has (anything goes wrong... get a new one!). For out of warranty service, there are licensed repair shops, like for Mesa, Fender, SWR, etc., etc.
However, +1, like most modern amps, if something really goes wrong with the guts of the amp (versus a messed up jack or something minor), you are correct, the typical repair would be to replace the board.
I would guess that most companies would not give out detailed schematics to customers. I've never heard of a company doing this, but not sure.
Unfortunately, there are no repair anything within 50 miles of me. There has got to be someone with a schematic of some sort, no?
G-K, Marshall, Fender are just a couple I personally know of that due and will send .pdf's of schematics? What does MarkBass have that is so special?
Thus far, Ampeg, Mackie, SWR, Hartke, Ashdown, Gem Sound, and I am sure I am forgetting a few have all provided me with schematics when I needed them. SWR and Hartke have been fantastic about it. So was Gem Sound (a little power amp I had). For the most part, from what I have experienced, most all companies have given me a schematic...
My mistake there. Interesting. I am surprised about that.
I would suggest contacting PM Peter Murray then.. maybe he will fork them over!
I guess I've been in the micro amp thing for so long (Walter Woods, early AI amps), that the idea of a user repairing an amp is a little out of my experience. Walter won't even supply his schematics to repair shops!
I do appreciate manufacturers who set up their own repair facilities, it does go a long ways towards establishing reliability and control of that aspect of customer relations.
But, I'm at the point where I'll only purchase or recommend for purchase products that can be serviced by a reasonably competent technician with commonly availible parts and tools. This does take some research to figure out.
The reason why is that manufacturers do change hands and some (ahem) go out of business. I don't like to be living with gear that gets used as a doorstop because it can't be fixed.

Traynor is superb when it comes to service manuals.

The offering of actual service manuals is rare!
Im curious, what do you ACTUALLY need the schematic for?
There isnt a whole of repair that you can do on your own with mostly integrated components on a Tiny PC board.
A big old tube amp, sure! but a micro amp?
Theres not a whole lot you CAN do, even if you could.
But you already know this, right?
Please elaborate on what it is you need the schematic for!

My tech called me yesterday. There are several parts - transistors that are blown. There is a bunch of stuff that comes off a schematic that is extremely useful to a repair tech. That is why there are schematics. It helps when the amp (in this case) needs repair. A pretty basic idea. Auto mechanics use a schematics when you radio doesn't work, yet I fix my own car without the dealership complaining.
Send it to a factory authorized MB repair center. Curious why you'd send it to a tech that is not MB authorized, or why the tech took it when they know he's not a factory authorized service center?
Sounds like a ripoff tech. I bet half the parts blown are from him trying to fix it.
Seems like if you want a schematic you should ask if it's available before you buy.
No car tech pulls out a schematic to work on a car radio - they swap the whole thing out. Service exchange, field replaceable boards, is the way it is now for most all electronic gear. These parts go back to the factory to get repaired or recycled.
Any stuff under warranty, if you work on it yourself or take it to an unauthorized person you run the risk of voiding the warranty.

Firstly, My brother and brother-in-law are my techs. Both have years and years experience. I trust family. Always have. I do not trust people to fix my equipment that I cannot talk to and do not know. My amp is NOT under warranty. I do not send my equipment anywhere. Period. It is funny that my tech found parts that have not been made in over 2 years!
