A solution to this hum was the development of a pickup which was created slightly differently to the normal ones. Instead of a single coil of wire wrapped round the magnets, two coils were used, but each wired to the opposite polarity, both electrically and magnetically. This meant that any electromagnetic noise that was detected by both if these coils was effectively cancelled out - like adding minus five and positive five, the answer is zero. This also had the added effect of creating a much fatter sound to the guitar too. Because these pickups were designed to cancel out the hum, they were named humbuckers, and are still extremely popular today.
The second common OEM tube out there is the Chinese Shuguang 12AX7 (Groove Tubes also sells this tube as the 12AX7C; Tube Amp Doctor has also sold this tube as a TAD 7025; and it has also been sold by Mesa Boogie). The Chinese 12ax7's are constructed with short, fat plates, like the Sovteks, but they have an extra spacer above the tubes, a big nickel colored brace connecting the plates, and a "halo" getter on top. Again, if you see a tube made like this, it's a Chinese tube, regardless of whether it has Groove Tubes or Mesa Boogie or TAD written on the glass. These tubes have a warmer tone than the Sovteks and more gain (volume). As a result, they work well in high gain amps.
