All I can find is a company selling them; Service Manual DB250, HTA250A SCHEMATICS ONLY
Never used this company so no idea.
Power supplies are very simple and don't be fooled by thinking you have short circuit output transistors, the internal gate capacitor holds the drain to source closed for a long time and must be discharged to read high impedance!
Found it, I new I had a copy in my archives. A very basic amplifier.
