Post by: johnk on February 06, 2016, 03:23:34 AM
here's a tube booster that I built capable of a bit of overdrive that I thought that i'd share.

Love this, man. Valve inside, SPST relay bypass, and it looks like the most trouble you went to was the polished enclosure.

Talk about your sleeper build :) :D  ;D

actually the hardest part was drawing up the PCB for the lighted pots and making the little 'L' bracket to mount the PCB with the tube socket.

That looks stunning. absolutely perfect etch and I agree with alan, the polished enclosure must have been a pain. Did you use any filters when taking the first pic or is it really having this epic glow around the lit up knobs?

That etch is beautiful!  Impressive innards, too!

thanks. no camera filters or anything. it looks exactly like the pic.
and polishing the enclosre isn't really all that difficult.

Wow! How is the L-bracket held to the enclosure? It looks like a rivet?

Amazing,!!!! Question,with no airflow, does it get too hot or is the enclosure one big ole heatsink?
Title: Re: AU-Drive Tube Booster
Post by: m-Kresol on February 07, 2016, 09:22:40 PM
now that I think of it, how do you get the voltage you need for the plates? similar to the valvetizer or the cleggster psu? sure did a great job fitting all of this in there and making it look so spacious at the same time

it only gets a little warm so it doesn't seem to need any airflow.

it's a modified Valvecaster so it doesn't need any more than 9 volts to power it.

Got any details on the L bracket?  I'm trying to figure this out for a multi build using the Valvetizer.  Thanks!

I would like some pointers about the polish finish.  I have never managed to get a result this fine.

Wow! Dude that's shiny! Only after looking in the pedal I realized the clever use of space to fit all the pieces in. Very Cool!
