Slightly before the CT100 came out, the RCA all channel sets were equipped with a tuner similar to it. It either was factory, or field converted. They were equipped 19, 25 and 31 strips. Back then, channel 31 was only proposed and never materialized.
The tuner had, 2 6BQ7's, 1 6AF4 and a 6S4, voltage regulator. The 6AF4 was used as an oscillator for both, VHF and UHF and lasted a lot longer, than the ones in the UHF only tuners.
I like the tuner a lot, truly overkill at it's finest.
