YET ANOTHER 5F1 Champ

[RWood]

I don't think I posted this one. After playing in church today I sorta got excited about it so here it is.
I am absolutely obsessed with 50s Tweed tone. (The 5b6 I just finished was my 5th tweed) I think I need professional psychological help. Maybe If I build a trainwreck it'll cure me.

This one has 15W transformers. Sometimes I use 5Y3/6V6 for overdriven tone, and sometimes CopperCap/6L6 for punchier clean tone.
12" Swamp Thang speaker.

It's nothing special but I am extremely proud of my tube builds after several years of building several dozen pedals.

I wish I'd started building amps before 50. This is like cocaine!!!

Very cool build. Be sure to post a gut shot if you have one! Nothing wrong with your obsession

What voltage measurements were you getting from your 5F1 clone and what is the dissipation like for your 6V6?

I have a clone and I was amazed that the 6V6 was dissipating 16 watts instead of the usual 12 watts.

Check out the Ceriatone circuit, he is using a power transformer with 320 0 320 and the cathode bias resistor is a 750 ohm instead of the customary 470 ohm.

B+ 360, B++290, B+++265
plate 1 12ax7 160, plate 2 155 (must be resistor tolerance differences)

Thanks for your voltage measurements. My amp had 380VDC on the main rail with a 330-0-330 secondary on the power transformer.
