As mentioned in a previous post, I've recently acquired a Heathkit SB-101 station. The amp is in good operating condition and the transceiver works but needs some TLC. I've been going through the final test procedures specified in the construction manual and am wondering what tolerances are OK with respect to the various resistance and voltage measurements. Clearly the components have aged and the measurements aren't going to be spot-on so I was wondering how far off they should be before I go looking for a faulty component. The major issue with the transceiver is that the 28.0 - 28.5 mHz crystal is bad, however the quality of the reception seems to fluctuate. I've made a couple of contacts on 20m so I know that both XMT and RX do work. Output is 100w +/- into a dummy load on all band switch positions except 28.0 - 28.5. Also, the meter needle only wiggles a little when in the s-meter function.
