Hi Guys,
Here's the improvements I'm thinking of:
Replace Output transistors, electro & tantalum caps,
Remove protection circuitry,
ac bypass bias chain with a cap, 47uF?
Some Q's: Is the diode on the - input of the LTP necessary?
Are all the HF roll-off caps necessary? or is this symptomatic of dodgy layout? (C704 at 2200pf seems high?)
Any other suggestions, or should I forget it and use the case/ps/heatsinks for something more modern?
Thanks,
Pete McK
