Hi all does anyone have a readable diagram for the power amp driver board for this, or its other derivatives i.e ma100 bass amp slave 130
that they could forward me please

I do not think they exist but I was involved with designing the modified RCA amplifier with H&H. What is your problem with it? My memory is quite good.
ma 100
Just acquired two driver boards and want to use to make a slave amp just need to find the pin outs to the pwr transistors i have got a poor copy but its virtually unreadable

Tip29 C = 2n3772 Top Collector
Tip29E = Top Base
Junction R33/4 = Top Emitter
Tip30 E = 2n3772 bottom Collector
Tip30 C = bottom Base
junction at -ve rail fuse = bottom Emitter
Hope this helps.

The schematic of the MA100. Not the best but useful.
All by all, HH amps were very well build and very neat.
In the last 35 years I had about 10 repairs. all minor problems apart from one I used as a test amplifier and by mistake connected the output to the input.
I have (had) about 10 pieces here. All guitar amps and combo's.
With pain in my heart I had to sell them almost all due to space problems.
