that was semi-official repair policy for apple II computers in the
minnesota education system... turn it off, lift it up a foot or two, and flat-foot slam it back on the table. oxidation and heat popping on the tin-socketed chips, you understand, and the machine was well enough built so you could get away with it.

The fact is once you mention "tubes", folks should realize that the thing may indeed not be well tuned. I'm trying to think if it is the GE Master II ... but it is a VHF rig and the cavities used to grow "crystals" in 'em and detune 'em. One guy showed me a quick way to fix it (yes, you can go in with a q-tip). He picked the radio up and banged it on the bench about 3 or 4 times. Suddenly, it no longer took 4 uV to get a decent signal. It was down to 0.25 uV. I did have to clean my shorts out the first time I saw it, however ![]() I was given an old SP-600 which had been under salt water for a brief period of time (I got the radio in 1968). I ended up replacing most of the components in the whole front end as it could barely receive local broadcast stations. It worked fine after I did that, but it was a real mess. Easier to buy a new receiver these days (prices are reasonable and if you figure my time, I was probably making about twenty five cents per hour fixing that slug!). Of course, that was back in the late 60s. Figure a grand buck and a half an hour in today's wages ![]() however. 73 from Rochester, NY Jim " --- Outgoing mail is certified Virus Free.
