ELC7? I need help to identify this valve

[pingfloid]

Hi,

I am rebuilding an old guitar amp, but I have trouble to identify the output valve. There is a mark "ELC7" written with a pen, but I can't find the specs for that valve. I enclose the picture.

The amplifier have a EZ81 rectifier and a ECC88 pre-amp. The supply transformer is 300+300V.

Any clue?. Thanks 🙂

...and a ECC88 pre-amp

Sorry, I mean ECC81 😎

Looks to me like an ECL80-something, probably 82 or 86.

How many pins ?
Perhaps a perspective effect, but looks like a 6AQ5

If it has 7 pins then 6aq5 / EL90 seems like a fair possibility. 9 pins? I have a 6bw6 and a 6cl6 with the same rounded anode style although they look a bit shorter than the one in the photo. All the ECL series valves I've seen have a different style of anode construction with a more rectangular shape and fairly wide flanges joining the two halves.

I forgot to mention... It's 9 pin.

Here is a closer picture

Looks like an EL84 to me.

Have a look and see if you can identify the socket connections, which pins go to the heater, cathode, plate etc.
