Would like to check if the resistor connected to the LED is a 560 Ohms or 5.6 KOhms? In case I want to have 3 more LEDs for different input indicators, and how to resolve additional power supply to the LED (3 more 6.3v?)? Also you have mentioned a relay circuit is required, any recommntation on this relay and where to get one? Should I install one more power transformer for that additional 6.3Vs?

are you happy with your tubeamp M7 , i like my M7 too ,[/quote]
Hi kinkin,
I like it much. The performance is beyond my expectation after I've added the 2 pairs of 0.1u and 0.01u Jensen caps. I've learnt a lot of things from the course.
Will you join the tube power amp course? I've told William to transfer my UCD quote to the tube power amp, hope to see you there.
Btw, thanks much for your help on building my chassis.
