Hi Jim
I had Cardwell make the one in the 2X8877 auto tune amp.  They gave it a part 
number, #154-16-17.  It is the 4500 volt series.  I made the one in the single 
tube amp from a 245uf cap and split it with spare parts.  It took some thought 
and careful machining.
73, Paul

Now that I have found some 3CX800s and sockets (thanks to the list)! 

I’m looking for a 2 section air variable tuning capacitor like in the Alpha 

1 section around 50 pF and the other section 250 to 275pF. I’d even take a 2 
capacitors as long as I can hook them end to end (larger cap in the front) as 
seen here:
Only problem with this is the assembly gets a bit long... So the dual section 
would be best.

I quickly looked on the Oren Elliott page but I don’t see any pictures or 
values. If someone has a part number, I could get one from them.

Thanks and 73!
