[BC] Looking for Capacitors

[Tom Spencer]

Which LPB transmitter?

The tube rigs were on-channel, but the SS rigs use a carrier x6 
crystal.  In either case, the TX itself should have been built for the 
upper third of the band; there are filters in the output to block 
harmonics and sub-harmonics. 

My 25B got butchered by the previous owner because he wanted the 1280 
kHz (640 fundamental) output as well - not realizing he'd also be 
getting 2520, etc., as well.  Ooops!  But now that I've rebuilt the tank 
and at least a couple of orders of LPF, she'll crank about 0.8A into a 
50 J0 ohm load; 375 VDC on the plate and about 125 mA Ip, according to 
the meter...  Or just over 30 watts.  The SS transmitter I have is also 
low-band (730 kHz)

Hmm  Lemme think - I also have a couple of RS tx's; they use a X4 
crystal...  Nope.  Thought I remembered that some of the x6 LPBs crossed 
with some of the x4 RS XTALS; they do, but not at 1530....

Anyway, the XTAL you need for a SS LPB is 1530 x 6, or 9180 kHz.  The 
tube rigs, remember, are on-channel.

Sorry I can't help more...
