Needs help Tubezone Poseidon

m12ax7 · 23rd January 2011, 07:51 PM

Hello...

Several years ago I purchased a set of Poseidon driver boards from Tubezone.

I did not receive two of the 47k 2w 1% resistors. I called and was told he would "drop two in the mail" weeks later I e-mailed and received no reply.

Shortly thereafter I was graced with twin grand daughters which led to the loss of my workshop. My project was put on hold. Now, years later cleaning shelves I've uncovered my "stripped" Dynaco MK3s and this un-finished project.

I've spent time on line looking for these resistors and haven't found a source.

Help! I've heard (but don't recall from who or when) that the value of these two resistors isn't as important as them matching.

Any one know where I can purchase these?

Thanks! that was fast!

I swear that last time I checked mouser they had either nothing listed or marked out of stock.

I've another question about the driver board. It's marked as both tubes being 12ax7s but the schematic calls for v2 to be a 12BH7 and I recall being told that a 12AU6 would work also.

Anyone using the Tubezone board and have played with different tubes?
Opinions?

I have a Audio Research SP3 which has plenty of gain, would it be best to use the 12AU7 in the V1 location?

thanks!

I had the Tubezone board on my ol' Mark IIIs and used a 5751 in V1 with a 12BH7 in V2.

Balancing the tubes was a little time consuming with the little blue screw-set pot.
