Yes I know what you mean Trev...
Well I finished the JLH apart from making the lid.....fired it up & no beginners luck I'm afraid! I had one channel only getting warm ....after a bit of probing I managed to get this down to no chnnels getting warm
I think the problem probably lies with my off board mounting of the transistors..as the power supply is putting out 33v I'm away for a few days now but will get back on it next week ...re check all my soldering & drill out the mounting holes on the heatsinks a bit more...I have a feeling I may also have toasted a couple of the transistors as I heard a muted double crack on powerup like a static spit....ordered some spares...good job they are only 79p each!!
If anyone has any thoughts on simple JLH diagnostics let me know!

Mike
