Thanks for the message board. I've read it from front to back and feel like I've learned a lot of history in a short time.
I recently aquired K250-1 with 2x15 cab (CTS drivers). Previous owner was completely up-front "it don't work; I bought it that way; never had time to look into it". I proudly recanted "I ain't scared". Heck, I went to a Tech school in the '70's (studied electronics). This aught to be fun.
Then I got it home and opened the chassis. Now I'm scared.
Someone attempted some sorta repair already. They decided to replace only ONE of the three bad output transistors (duh); soldered in some new resistors that (questionably close to correct value); then musta called the fire department after power-up. Now there's holes burnt through the pc card. Not a pretty site.
Before I give-up and go shopping for another head, I figured I'd float some questions:
Q: Does anybody have a Kustom boneyard where I might find a clean PC 5065 that I can buy?
Q: Luckily, my chassis already has schematics glued to underside of the cover. But before I invest a bunch of time chasing traces all over the board to reconstruct a component placement diagram, does anyone know of an existing source for this drawing?
Q: The faceplace of my amp has "Hitachi" embossed right into the metal. I mean, it sure looks like a factory-type thing that was done intentionally. It's significantly smaller than the writing that says "Kustom 250" and is positioned directly in the center; along the bottom edge of the faceplate. What the heck did I find?
Thanks in advance for your wisdom.
