Hi,

That looks pretty cool!
How do you align the pedal under the laser. Is there a 0,0 coordinate?

Thanks

Hi,

Smallbear pre-bond is what I use and used for 10+ years. If you are building amps though, use the aerospace grade teflon coated wire from tubedepot. The teflon is extremely hard to strip and is not a pre-bond, but the coating will not melt and the wire is excellent.

Thanks

Hi,

If you want, send it to me and I can try and fix it if you would like. I build these regularly and haven't had any problems. If need be I have some nice russian diodes I can put into it to make it work if something is wrong there.
Up to you, but happy to help.

Thanks
Ernie

Hi,

I was wondering which 6111 tube supplier(s) you had the best luck with on the tubes. I know duds happen, so not trying to single out the one that had the bad one.

Thanks

Hi,

Can you post a pic of the board?
Q13 is the one to socket and try a different transistor if you have some spares.

Thanks
