Title: Hello from NJ
Post by: Jon102198 on February 24, 2026, 01:34:35 pm

Hey folks. After seeing every question I have ever asked the googles point me to here to someone who solved it a decade a go, I figured I should just join!

I started tinkering with tube amps and guitars about a year ago, mostly out of curiosity. Managed to fix quite a few and flip for profit. Now I'm about to embark on my first build, a 5F1 based on a salvaged husk that I have on a DOA Vibro champ XD with good iron, cab, chassis, speaker. I will base the board on the Hoffman design here but rectify with diodes. 

I have a lot to learn, this all seems like wizardry to me still, but I'm having a blast!

Welcome to the Hoffman Amps forum

There are many different boards on this forum for different topics.

The Tube Amp Building - Tweaks - Repairs board is where you can post amp questions.

That board is listed here.
