JLH 1996 class A aaudio power amplifier version with MJ15003 outputs.
Biased to comsume 10 watts but can be increased depending on which heat sink you use.
I have 3 off up for sale.
Requires a +/-15VDC power supply and a 0.5 degrees C/watt heatsink.
£18 each plus one lot of p+p per batch.
p+p is £4.20 to UK £12 to Europe and £18 to rest of world.

Hi,can you tell me a little bit more about this amps.Which driver tranzistor are used,how do you made quiscient current control and Dc offset??
MJE340 is driver transistor.
There are two presets, one for DC offset and other for output bias control.
See diagram below:

See diagram below:
Drivers are MJE340/350.
Outputs are MJ15003.
Two trimmer resistors, one for DC offset and other for bias current.
Had a couple of spare pcb's so seemed a shame for them to just get shelved so built up another couple.
Same price as in original post.
Ignore 1/3 amp on schematic it should 1.2 amps.
