It appears that Ocean State Electronics has some of the variable capacitors that BG Micro sold out of about a year ago. Assuming they are the same (and I'm almost certain they are), I can say that they work very well in the HBR receivers. A few bucks more than BG Micro sold them for, but still a bargain. Part number BC5G. http://www.oselectronics.com/ose_p59.htm Regards, Darrell,WA5VGO
