If you know how to use a scope, than going thru the amp should not be a problem as judging by your PC board numbers you posted the 5000 serise numbers where in the late k100/k150 model range and semicondutor wise you can still get parts, although if you find you need one of the 14 pin duel op amp ICs(NTE725 or ECG725) you have to go surplus searching. You can try calling this guy( Bob Monday) at 5 which is his work number(if he still works their)as he was intrusted with a load of Kustoms schematics when he was working for them when the went out of the market. I went to the Broadway music site and he does not list schematic for your PC boards. I would first check the amp by hooking a volt meter set to read 50 to 100 VDC and see what you have when you power the amp up, if you get a quick flash of DC voltage I would than set the meter for low AC volts and then plug in and play thru the amp and see if you show any AC volatge which would be your auido signal. Having no turn on (power up )thump with a kustom that lights up is strange as most problems are in the driver/output section and if the speakers a working you would be hearing a 120hz hum. You said that it had no numbers on the circuit boards, but if you could look again - if you can find PC numbers of the circuit boards, maybe someone has a schematic.Īlso, try to post some pictures, maybe someone will recognize it. Internally they were the same in every way - including the "Kustom" name and PC # on the circuit boards. The early Kasinos (approx 1971) were virtually identical internally to their Kustom kousins. Yours could be similar to one of these three examples from 1970: Kasinos having the plexiglass faceplate would be in the 1970 - 1973 time period, so there is good chance their circuits are the same or similar to an equivalent Kustom. They had plexiglass faceplates like the early Kasino's (such as U100-P Club 4 channel PA amp). I have seen them on ebay though - they had the Selectone and Selective Boost and the amp section is maybe one space high. Recently someone asked about a Kasino model 200 4x12 powered cabinet, and no-one seemed to know anything about that one either. It is not in the "Literature" section of the website either. I don't have much info on the model that you have (Kasino 100). Many thanks for any and all help offered. We've been revisiting our surf rock origins and would love to bring this beast back to functionality, if at all possible. It belongs to a friend of mine, who's owned it since high school (several decades ago now, unfortunately!). I haven't sat down with a scope yet to follow audio through the head yet, as I'm hoping to find schematics to make debug easier. The amp powers up but has no output, so the fault could be anything. Does anyone know what this amp is officially called? Anyone have schematics for it? From left to right it has pots/rotary switches labeled "Volume", "Bright", "Treble", "Bass", "Selectone", "Selective Boost", and "Boost Volume". The amp has 1/4" inputs labeled "Foot Switch", "High", and "Low". This includes any markings on the amplifier and control/panel PCBs. Other than the branding, the only model info I could find is the number "100", which is embossed on the cab. I recently acquired a defective guitar amplifier bearing the name 'Kasino'.
