Re: New build Complete: 45W, four 6V6, non-HRM

The same plate impedance! That a great half power method. Thanks all! I think I also saw this approach on a Carvin 100 water.

Xtructo, thanlks! I always wondered what that really does to the impedance of the primary? And if it doesn't create a mismatch????I guess ill have to try and see what it does.

Re: Powertube bias Bypass Cap value in 5E3

It probably has more to do with the need for a higher voltage rating on the stock 25/25 cap.

Re: Frugal Amps / lead dress

I read on TGP that Brown Note has people waiting for 22 Months! They are not happy.
