9v /12v Tube Driver Veroboard / 100% Complete + JFET Version

[spudulike]

Nice layout, 10 holes shorter

Ive been building mine, either something is wrong or when ive wired the tube ive got the holes mixed up on the socket , no bypass sound either, led works thats about it
No light from the tube, but im testing from a 9v battery not psu

Took me all bleeding day, Ill try reversing the tube pinout

[finkfloyd]

Well Im stumped, I do get a bypass signal but not an engaged signal, (soundcard mic in, was on mute)

I tried wiring the tube backwards and nothing different, and the usual of checking traces etc..

Ill have a more indepth look tommorow, this has taken too long, I dont want to try the other layout just yet..

Also Spudulike Is you layout verified, I mean have you built it?

I'd be interested in knowing if the spudulike layout is verified too.  What kind of tone would you get from this effect.  Could it do a good clean boost?

I just finished the non jfet version on a pcb and it sounds awesome.
I am a floyd nut and this was a piece that i was missing and didnt want to shell out
ebay prices. thanks

Are any of the two vero layouts of the tubedriver verified?

I would like to build one.

Fets are not just drop in replacements they require different biasing than tubes. Trim pots make it much easier to adjust but they take up a lot of space on vero.

A simple trick to avoid trimpots is to socket the bias resistors. You can then easily try different fixed values until you get the bias right.
