Timtube c-hing, do you mean EL12 can be used as substitute for 6L6/KT66? That said amps using KT66 (with appropriate adaptor), such as Quad 2 or McIntosh 240? Mine is not spez. version i.e. without cap on top of the tube.

There are different versions of EL12 with different max voltage rating e.g. EL12/325, EL12/350, EL12/375, EL12/425, EL12N etc.

You have to make sure the circuit operates the tube within the max rating and it can replace 6L6, KT66 and even EL34.

For example, the EL12N will work in a Leak TL12.1 and sound better than KT66.

Timtube ching, how to identify each of the different versions? EL12N is clearly shown on RFT. How about other makes such as Telefunken? How is the sound quality of RFT EL12? 401a is hard to find, let alone the price tag. Any economical recommendation? Also have some EF12, AZ12 and EZ12 and want to put them to good use. Thx.

Timtube,
Thanks your information. I had search some klangfilm amplifier model is no 15ohm output select, only 200ohm 100v output, in this case any others output trans can covert it? or any others way.
i interested the klangfilm amplifier, i am leak tl12 plus user, i want try el34 tube sound , i desire try klangfilm , but i only get few information from internal, can you share some info n schematic .
thx

If it is the basic EL12, then you should assume the max voltage rating for the plate to be 250V only.

EL12N can take max 425V and is the worst sounding among EL12. But it still sounds better than GEC KT66 and most NOS EL34.

The best sounding EL34 amp from Klangfilm is the KLV-502 and it is one of the best sounding EL34 amp ever made if not the very best.

KLV-408 is the 2nd best Klangfilm EL34 amp followed by KLV-408a. Even the KLV-408a sound much better than Marantz 8B, which is perhaps the best known EL34 amp in the world.

To my knowledge, all Klangfilm tube amps have 15 ohm output. You may have confused them with the Siemens 6S-Ela tube amps.

Some 6SELA has 16/8ohm output but need to modify by yourself.

408 sound much than better than 408a, the only different is the choke.
If your speaker is 8ohm, I recommended to use 6GB8 instead of EL34.
No need to change circuit.

I had search this web sitehttp://www.tube-classics.de/TC/Klangfilm/OPT/OPT.htm , any others web information can share .
thx
