Re: 2-B 50kHz Alignment Question
Check the values of C50 through C52. It wouldn't be a bad idea to check the resistors around the tuned circuit, as well. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent

Yes, the SK is correct, but the sale and mailing of his CD's has been handled by a family member since then, up until now, apparently. I ordered and received some since he became SK. Tom K0SN

Re: 2-B 50kHz Alignment Question
Make sure that you have it on the right pin. I used about a 1V signal and had no trouble. 73, Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent from Proton Mail for iOS

Re: 2B S meter
The S meter in the 2-B is identical to all of the S meters used in the R-4 series, and they¡¯re mechanically and electrically identical to the plate meter. Normally, these meters rest at S-1 or 0 mA

2B S meter
Is it normal for the 2B S meter to sit at about S3 with power off? I can zero it OK with power on, but it always rests at S3 when the power is turned off. Ken, VE3FIT
