6AB4 triode equivalent to EC92 is half ECC81 and can be used in audio preamps.

"Power" tubes like 2E26 or 2E24 with around 10W plate dissipation can be used in OTL headphone amps as cathode follower.

As was already mentioned, the 7C5 is a Locktal based 6V6 equivalent and the 6AB4 is 1/2 a 12AT7. Match up pairs of 7C5s and 6AB4s and you are on your way to building an "El Cheapo", which is an "integrated" amp.

The 6U8 is a triode/pentode. I can see a nice "unity" gain line stage using a 6AB4 cathode follower loaded by the 6U8's pentode section. The triode section of the 6U8 would be used in a B+ shunt regulator.

I recall 6360 being used as the RF output tube in smallish (10 watt) VHF FM transceivers.

2E26 is another small RF output tube.

Sounds you like got a nice find!

IIRC, 8032 and 8552 are variants from the 6146 family tubes, 8032 being a 12 volt 6146A and 8552, being a 12 volt 6146B.
