[Amps] Anyone have a 160M Tank Toroid for a Alpha PA70 or PA70V?

[Mike & Becca Krzystyniak]

Thanks Carl... I will use the 80m core design as the baseline.

    What I need is a target inductance for the 160m core.  I think a turns
count from the 160m core on an early model 70 or 77 series amp from Alpha
would get me close.  

    Does anyone happen to have a PA-70/V or 77 series amp that can tell me
their turns count on the 160m tank coil?

Thanks...

I would think the toroids and the coil is the same since the 3 tubes are 
similar and on 160 nothing is that critical. The toroid itself is likely a 
Micrometals #2 mix. Go to Amidon and get one of the same size, use Scotch 27

tape and Teflon wire.
