Hi there all,

I just finished my new PP 6B4 amp. It uses the ST70 transformer set on a prototype stainless chassis, with brass and stainless hardware. I doesn't mean much, when I say that it's best thing I ever heard, because I haven't heard a lot of good amps, but I have experienced (and participated in as a sound technician) a lot of live music and theatre over the years. It has an incredibly rich tone with a lot of interior subtlety.

The circuit is a 6S4 cascaded into a 7044, driving a Hammond 124E IT in a parafeed config. I basically copied the topology of the WE86A. I call it the Franklin 15.

This was taken before the amp was wired. Now it's a thing of beauty with all the tubes lit up at night.
