I possess a Kustom 200 PA that is in need of repair. Is there anybody, or company that does this sort of work. I live close to Austin.
Thanks in advance for any advice.

Your best way to get this done right off the bat is to locate a electronics repair shop that handles repairing high end home audio gear and in restoring the older type tube gear.
The next way to go would be to find a music that sends out its gear to be repaired to a outside source.
Be sure to inquire from the music store how the outside company's track record is on fixing solid state gear.
The last way to go would be to try out a music stores repair capacity if there tech is a young guy who is a parts changer and has little trouble shooting knowledge.
These amps are not hard to work on so don't let anyone give you crap like that, and all the parts that might be needed to fix it can still be had even though it's a minimum of 50 years since that amp was born.
In the technical section of this site we have the needed schematic's to repair it.
If the repair tech needs some pointers to help him or speed up the repair just have him post his questions here.

What I wanted to say in my first reply to you is a music store with a on board young repair guy will likely not be a good choice to work on your amp, especially if it has no output and is blowing fuses.
Thanks for asking! It's a Kustom 200 head with 4 channels. The amp turns on with out any blown fuses ect, but all channels have a loud buzz, plus the volume isn't as loud as it should. The problem isn't localized to one channel, but to all of them.

Well no blown fuses is a good thing .
It would seem to me that the amp needs to have all the electrolytic caps in the amp replaced .
This is very common with amps of its age when the amp just sit's for months without being turned on.
I know what electrolyte capacitors are, and I guess I could take a stab at replacing everyone of them myself; however, I'd really hate to screw it up worse than it all ready is. I'll take a peek inside and see just how many there are.

I would not do that if I where you!
I believe your issue is on the driver / regulator board on the rear wall of the amp and to work on it requires removing one of the big main power supply rail filter caps and unplugiing the output Transistors .
Boy...I'm having a heck of time with this web site learning how to navigate around in it, ha ha! Anyway, in response to your message, no, it definitely would not be wise for me to try to fix it myself. I read some where that there may be schematics available on this site, so I'm going to try to locate one of those first, then locate a repair shop that's willing to tackle my amp.
