Re: Dumbleator Build Questions

I use fr4 1/8 because 1/16 is to flimsy for me.

Re: This Hurts My Eyes!!

I didn't know better when I was young and sent a Silver face Super Reverb to Torres for his superior amp designs ha ha.

It took me until I started working on amps many years later to discover why the amp sounded so odd. It was out of phase do to Torres gain mods.

Re: Trainwreck power supply/filter cap board

I used to build Rockets with two of the filter caps incorporated in the circuit on the tone board and punched chassis hole for 50/50 can cap or put remaing caps on small board.

Re: Brownface bandmaster ultraponic build

I messed up it is not a 5e7 it is a 6g7A 50w Bandmaster non-reverb.

The chassis has 4 power tube holes so it could be used as a Twin 6g8 also.

Re: A simple "master volume" mod -- adjust PI bias

Colossal Dave

I remember clearly our working on my amp a 50w 6L6 Rocket Reverb using that watts control in the PI like the Carlsboro 60 amp. Still have the amp and still love the tones.
