Recently had some new problems occur with my CBK 20B:
The RF decoupling capacitors on each stage of the TRF circuit were going bad. At least one or more were shorting out. I neglected to replace these initially because they were in nice metal enclosures, but after watching some of bandersontv's videos on re-stuffing caps i decided to re-stuff these.
The caps look great, but the radio still did not work properly. Stay tuned for more...
