No problem. I'll forget about EL12 spez. I'll just use EL12 or EL12N.

BTB (https://www.btb-elektronik.de) has them for about half that (but with potentially higher shipping cost).

Thanks Oskari. Good to know there's supplies around. I actually quite like the cheaper EL12N too.

Good I don't have to put on plug in anode leads.

So can I use EL12 in the first stage?

You can try it same pin out and see how it sounds.

Cool but I will essentially be using EL11 in the 1st stage and EL12 in the 2nd stage.

That's the plan.

 

[2359glenn]

Yes I have to look up the transformers and get prices. I think it will be a little more then the EL3N amp.

Ok no worries.

All pistons fired up and ready. I have:-

Philips Miniwatt EL11 - 1 pair
Telefunken EL11 - 1 pair
Telefunken EL12
Siemens EL12 (identical looking as the Telefunken.)
RSD EL12n - 1 pair

Should last me a lifetime.

Nice project, UT. Looking forward to the future review and pics!

I'm quite amazed at the change of events because I was going to get the same amp as you, right down to the same caps.

This is not going to be that much different from the EL3N amp. You could say they are close cousins except maybe Glenn is getting different transformers to accomodate the more powerful EL12.

EL3N from Holland. EL11 / 12 from Germany. Interesting variations.

Socket wise both using Yamamotos so both should be equally good.

This amp will use the same transformers as the 300B that are really the same as the EL3N except for the primary impedance.
the power transformer has to be different then the EL3N because the EL12 draw more current.
Power will be the same transformer as the OTL I think right now.
Output power will be 8 watts the same as the 300B. With much cheaper tubes. I like that!!!!!

Drool. You are getting me excited now.

Nice looking Telefunken EL11, EL12 and EL12n.

Yeah absolutely, much cheaper tubes than 300B.
Great project indeed.

This should be good at powering speakers also with the 8 watt output.
