I'm working on a Kustom sound reinforcement amp. Does anyone know where I could get a replacement PCB Part #PC-5065? This is a Kustom XII SRS Tri Amp and has three power amp sections (all three are PC-5065) and one is burned up pretty bad.

Welcome to the place!
The PC5065 is the basic 125 watt power amp board that was used in many of the later Kustom heads, like the 250 metal front amps. The only source that I know of is to salvage the board from another amp.
How badly burned is the board you're working on? Or are you thinking it would be easier to swap out a board than to replace individual parts?

It fried the board, it left a chared hole right in the middle and i think its best to replace it. I think I'm not that good with replaceing individual curcuits. THANKSSSS STEVE

I'd just look for any of the tolex covered amps that were the 130 watt output. K250's had the same board. I see some of the Bi-Amp Kustoms on craigslist or ebay and they go pretty cheap. I think they used that board right up to the time they stopped making the kustoms. The lll monitor amp, the X power amp, the Vlll and Xll Bi amp slave amps, The lll lead, lll bass amps, lll PA head, and a lot of the blue face Kasino's in the 130 watters.
Good luck on fixing it. I had a board and sold last fall. I still have one that is in my lll monitor amp, but the amp is still working, so I don't think I can part with that one. I do have the rack mount housing and filter caps, and 7 band EQ that is missing the power amp and transformer. Still has the bridge rectifer and some other misc. parts if any one has a use for it.

Yup your absolutly right. I don't have the equipment or know how to test them, but I have a friend that is going to. Whom ever had this amp before me burned it up real bad and repaired it by hand wireing and replaceing resisters and such. Again your right, I can replace some parts, input or output jacks and resolder broken solder points on power resisters and pots and things, but I'm not a teck by no means. I really thank you for your help, and especially the heads up on the power transisters. THANKS AGAIN STEVE

I used to repair those way back.
Any of the III series, lead or bass, will have it. The LF section of an VIII biamp will have it, many of those fried the HF section.
As far as the outs...they are 2n3055's...dirt cheap...just put in a new matching set. I used RCA's, 4 should be less than ten bucks.
I did repairs for the String Shoppe in Columbus we sold hundreds of those.
I sold enough Kustom stuff to spend the weekend in Vegas with Kustom's head honchos. This was late 70's.

Hey liquidator, welcome to the place.
Your insight and history will be most welcome and useful here. A few of the guys here also sold Kustoms back in the day and any added info will truly be appreciated.

Yup Charlie was there.
At one point Charlie jokingly suggested he needed a loan...fellow from Chicago said Charlie could give him a Gretsch electric as collateral.
"You can put it on my sales floor, it won't go anywhere"
We sold a number of the FLH 15's. The cheaper model was MDF, our boss bought them and swapped in SRO's. Man did they weigh a ton...my back still hurts. Sounded good though.
One night of partying I dropped my wallet somewhere, had to borrow a C-note from Wayne. Managed to hit and paid him back an hour later. A C-note was worth a little more in those days.
Met Bud Ross around 78-79, he was thru showing off some Ross stuff. Have no idea why, we only ordered from him once.

Thanks for all the wonderfull info and help everyone on this sight has been. I found another kustom XII srs on ebay for parts and used a board out of it. Its made a couple of shows with 2- Kustom BI-AMP roll cabs I have and it kicks. Quite the tank to haul around tho I might add. Thanks for the schematics also. I've fixed my Kasino 250 bass head. I now have 6 k-200B-5's going strong. Still aint figured out the K-150-2 I'm stumped. Where is the low voltage supply comeing from on the the lower channel? The head has 2 channels one over the top of the other and the lower channel has very little signal getting threw and also the Trem/Vabra doesn't work. Top channel is strong and the reverb works. If someone has the schematics for this unit and can kind of email me them and even better circle the parts that may be the problem I would be very thankfull. Steve C. at cassent5150@hotmail.com
