Default EF86 replacement

Hey

Now that the price of EF86 is towering , are there some who have tried to replace the EF86 with EF184 or EF95/6AK5 or 5654?

Yes, I know that the pin connections / sockets are different.

Hi,

After testing, I have found the 6EJ7/EF184 to be very close in electrical performance and sonics.

My simple tests held true for pentode, triode and SRPP topologies.

Cheers!

I don't know how much Brimar 6BR7s cost these days but they were definitely designed as rivals to the Mullard EF86 (with a different pin-out, of course). There is also the 6BS7 which is the same but with the grid taken to a top-cap for even lower noise operation.

Hello, I build a version of Darling Amp (1626 SE Triode Amp) and I use EF184 triode straped as driver. The sound is very good, much more tha my RH807 (local feedbak).

If I name 6J32P I'm afraid their prices will go up and tubes disappear from ePay...

E80F and EF804 are good substitutes but may not be any less expensive, just
less popular... Different pinout on the EF804 at least

Get some loctal sockets and go EF40 (the EF86 predecessor with virtually identical specs) at a fraction of the price.

Ummmm... not loctal, it's that weird minature thing (B8A).

Cool thing is Shuguang is making sockets for them again, yay!

Cheers!

B8a is called "rimlock" because of that little boss on the valve base which "locked" into a corresponding depression on the "rim" of the base. Not particularly weird in the 1940s.
