hello tube people !!!!

i ahve a big ammount of tubes that got from police stock ....all of them brand new all of them jan types so i dlike if someone knows if any of these tubes can be used in line audio preamplifier ....

possible also some of them could be used in audio amps also but since i am a transistor guy dont wana bother with trafos and all that....

any suggestion or even etter schematic will be just perfect ....!!!!

there is a small example with what i have

7060--7167--2e26--8032--8552--6360--6u8a--em84--6ab4--6397--1ad4--7c5--2e24

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.
