Friends,
I am doing a repair on an SB 221, received here (Auburn) with a partially done 10 meter modification. Looking for some silver mica Capacitors 2 ea 22pf @ ~ 600v. and one ea 115 pf, SM ~600V The Silver micas are needed in a time squeeze otherwise I would just order them. Also, much less time pressure; a set of PS supply caps 8 ea, 270 uF , 500V These have a matching OD to the ID of the plastic capacitor carriers on the Heathkit. A snug fit in OD/ID Carriers but much shorter in length. If you don't match these ID/OD a reinstall/redesign package gets messy. Digikey P/N (ca. 2005) ECO S2HPO271EA I can get them from Digi Key but want to check local first, in case someone has a set. The Caps are to be used for a Drake L-4B. I had some for the L-4 but used those to hustle the Heathkit, out, back to making heat.
Anyone near Auburn /Sacto are have some, anyone need anything? I have lots of RF stuff but not these SM s.
Also, anyone have expertise and equipment to tweak some TV transmitter amp boards ( several varieties, about 20 boards with Heat sinks; 100 watts to 600 watts out
from 470 mhz to 432? I want to learn how to do that, and will trade for services... Here is what I have:
