Odd...

1)  VPA should be around 346 VDC.  Are you sure you are measuring either the output from the 1K 5W resistor or the input to the 6.8K 2W resistor?  450 VDC sounds more the output from the diodes or the input to the 1K resistor.

2)  I'm showing 0 VAC and 0 VDC on the speaker outputs (with no input, volume turned all the way down.  Can you describe how you wired your output transformers?  

Sorry I'm not helping much!

Mike

Hi Mike,
Your help was invaluable, thanks! After reading your post, I rewired the two amps and like magic the darn thing worked! It sounds great paired with my vintage Infinity RS6001s. Now to convince my wife that I need more effecient speakers! Wish me luck.

Congratulations!  I'm not sure how I helped, but....

I keep trying to work on mine, but life keeps getting into the way!  I'll be driving a pair of Klipschorn's (at 104 dB sensitivity, should be plenty of power).  I also have a pair of Klipsch RF-83's.  Should be fun.

If you like DIY, there are some neat single driver kits that would be fun to build!  Great imaging!  Great Christmas gift from your wife!

Best, Mike
