Title: TH Custom Effects Tube Driver 1.2 Modified to 12VDC.
Post by: Ekimneets on August 20, 2018, 12:42:02 AM
So, I ended up using an extra Tube Driver 1.2 board I had lying around as my Valv-E-Tizer 1.5 PCB's are lost in mail limbo somewhere.

All of the 47n box film caps were upgraded to 100v. Same for electrolytic. I wasn't sure about the electro's so, I upgraded those to 100v, as well. Why yes, that isvquite a large electro you see in that gunshot.

A heat sink was attached to the voltage regulator and ventilation holes were drilled into each end of the enclosure.

Right now it is running off of a benchtop power supply. I had purchased a hefty $15 Jameco wall wart, but it introduces a lot of hum into the system. Still on the lookout for a 12vdc 1.5a power supply.

Using an EH 12AX7 tube. It's a fair amount of distortion, but I love that. It covers up my atrocious guitar playing.

Nice build!
Yes that is a fat electro cap there...

Did you do the ventilation holes on purpose to be like 9 pin sockets?

Nice one! Like the orange/blue contrast despite the Clemson vibe.
Great job on the vent holes, too.

Yes, the vent holes were very deliberate. I'm not totally void of creativity.

I agree, the 9-pin vents are a great touch!
