The Russian 6P41S works very well, if the G2 voltage is limited to half the anode.
The connection of the base (both tubes are MAGNOVAL) EL506 and 6P41S is the same!

Default 6FM7 dissimilar triode

Hi

The 6fm7 is the compactron sister of 6em7.

The 6EM7 is getting costly in last few years hence the recommendation to look at 6FM7.

This is a vertical deflection amplifier and driver in a single bottle.

This is a very good sounding tube SE or PP, anode or cathode parafeed configuration - highly recommended.

TOO LATE!!!

$130 for 5 of them (6FM7) at 15% discount on Ebay!

The original 6EM7 look to be cheaper.

Glad I bought a box of them back when they were $1 each (6FM7, 6GF7).

Hi,

AES (tubesandmore.com) is selling them for 4.9 $ no need to pay inflated prices.

Good luck
