Re: Hoffman chassis 6V6 project
OK, I answered my own question by looking at their web site, thanks Mark. I see some price examples also. What did yours cost, if you don't mind?

Re: Hoffman chassis 6V6 project
$59.01 front panel and $50.57 back panel. Cost increased because I infilled the milled lettering with black paint.
I think UV printing is cheaper.

Re: Hoffman chassis 6V6 project
Thank you guys I appreciate the comments. Doug Hoffman's little chassis are very cool. I want to built another one with EL84's.
Re: Hoffman chassis 6V6 project
Are you going to do anything special to ventilate the tubes. I'm kinda surprised the tubes were placed up front rather than along the rear edge of the chassis.
Re: Hoffman chassis 6V6 project
There is no problem with the tubes being up front, 1,000's of amps have been running with this design. I prefer your layout myself with tubes on the back of the chassis.
Just look at all the Little Walter 22w, 50w, and 80w guitar heads out there with the octal tubes up front.

Re: Hoffman chassis 6V6 project
Finally I got this amp wired up, fired up and ready to do some playing.
I thought one of my Mikey head cabs would fit this but no I didn't pay enough attention to detail so will have to build a cab.

Nice! Thanks for sharing Mark, I always enjoy your builds. Great idea !
Re: Hoffman chassis 6V6 project
Thank you.
I adjusted the dropping string and sold it to a jazz player, he loved it and is not putting it in a cabinet he is mounting on wood.

Hey Mark,
How does the printed version compare with milled from FPE?

Re: Hoffman chassis 6V6 project
I like the "tubes up front" design. It can make for a really short run from the input jack to V1A. If you design openings or perforated metal front valence you can vent tubes and show them off for aesthtics.
