Tri-Ang VB449 dual overdrive

[tubelectron]

Hi All,

The Return od The Plate Craze !

Here is my Tri-Ang VB449 dual overdrive.

The plate comes from an old variable transformer for model trains on the way to be trashed at the end of a flea market : too nice to let it go !

Features :
- one single central control for the output level.
- the right FSW is FX in/out (amber pilot upper).
- the left FSW is Blues/Rock : 2 overdrive presets (red pilot lower).
- 9V internal battery and/or ext. pwr.

Pictures :






Schematic and layout - the starting basis is the DOD250 RI "Yellow" :




A+!

great looking boxes - i really like your style!

Thanks artifus,

I suggest to replace the "Rock" serial attenuator 22K resistor with a 100K internal adjustable pot, in the case that your amp may need a different balance between blues and rock than mine. 22K is convenient with a SF Twin or Deluxe Reverb. Doing so, you may change the value of the "Rock" treble tamer 2n2 cap to maintain the same tone correction as they are somewhat interactive.

A+!

Your recycled box builds are fabulous, so retro-cool

And your drawings of circuits are lovely too.

Thank you, Guys !

It's the only acceptable way that I found for the decorum of my stompboxes : the "Retro-Cool" style as you (kaycee) smartly named it (I will record it) is my "fave by default" (well, it could be worse !) but yes I must confess that I love it too...

Nonetheless, I always stay amazed and admirative seeing the "pictures" and "show me your 1590A" sections... Especially as I am definetly unable to compete with those remarkable finishes !

A+!
