Here are a few I have saved. I think there were some ax84 amps that used parallel output tubes. There are a few on the hoffman amp site too. Let me know if you need a board built, I build boards on the side.

Re: recommend a good DMM??? That won't break the bank??
I bought an Ideal multimeter, google 'Ideal multimeter'. I bought a brand new one off ebay for about $60, new they were a $110. They have many different models. I believe Loews sells them too.

Re: Q - Rocket Board Size?
To M Fowler,
So how does the 3 differnet Rockets sound? I am curious if the one with Sozo's has a better sound than the other 2 you have.
Dave
And thanks again, Mark. I have on occaision changed my boards from one run to another to accomodate bigger components that i buy (like SOZO).
