Just one more Joe. Just one more rectifier.....

After the rather intense bidding of the Osram U52 which I did when I was having dinner at a restaurant, I just need another gz37. Whether it's the fat bottle or the skinny Mullard remains to be seen.

I have 7 octal gold plated socket savers from mrsxuling for sale. It's been used only once. I'll take 10% off mrsxuling price. Don't need these now. My tube rolling on the OTL is over. I'm set on 6 x 6bx7gt as power tubes and they will remain there. Only the driver gets rolled now and even that isn't happening a lot now. I'm just enjoying music.

So if you need 7 golden socket savers, PM me.

Hi UT,
In addition to the ST type EL11 and straight glass TFKs, there is one more variant - a Loewe-Opta small size ST type tube.
IMHO the best sounding ones are the Telefunken ST type.

Mordy are they on sale? Provide link please. I have a specialised EL11 / EL12 spez amp so I have to ensure I have enough tubes to last 3 lifetime.

Hi UT,

The small Loewe-Opta are quite rare and I only have one. A quick search on eBay yielded a single offer:
https://www.ebay.com/itm/GEPRUFT-Ro...341415?hash=item5458479e27:g:XCoAAOSw--Fa-HEQ
It says that this tube has been in their warehouse since 2009 - could not be too much demand..
I have had good luck with Google translate in understanding offerings and in communicating with sellers.

BTW, for you to complete your collection of EL12 Spez, I found a picture of a TFK "Plattfuss'" one:

Could be a mistake though - maybe EL6?
Plattfuss=flat foot=side contact

It's quite run down looking so I'll stay with minty looking tubes.

I also think that it is too expensive, and that the TFK EL11 sound better.

What driver are you using?

Currently Tung Sol 12sn7gt black glass round plates.

Nice sounding tube.

This EL11 - EL12spez amp I am building for you will be the first amp that I sold that didn't listen to the tubes/amp first.
Except amps for Stavros but that is different I gave him most of my experiments. Your OTL with all the output tube sockets
Stavros was my Ginny Pig.
I do expect the EL11 - EL12spez amp to sound great!!

Didn't you do the same for the 45 amp for Tyrell?

It's ok. I'll let you keep the EL12 spez amp for a month to listen. Make sure you get to enjoy the fruit of your labour.

I think it will be great. These are great tubes; Look at this vintage Telefunken tube amp using EL12 spez.

One RARE vintage Telefunken ELA V300 tube amplifier. Made in Germany in the 1950s. Made for PROFESSIONAL use. Output power is 25 Watt from 2x EL12 spez. PP and 3x ECC81. With high quality microphone transformer. For all common main voltages between 110V and 240V. See pictures.

If I hadn't listen to these tubes before I wouldn't dare plunge in but I have quite extensively. In an amp not design to run it but it sounded good. I've never tried EL12 spez but I've tried EL11, EL12, EL12n both as driver and power tubes. They sound dynamic, clear, bold and energetic. It's like EL3N with the heavens open.

What you do will be totally different though. Transformer coupled with quality Lundahl transformers that you use in your 300b amps. It will be special. I look forward to my 1st transformer coupled amp.

 

[UntilThen]

I was thinking of having preamp out instead of speakers out. Have you done any EL3N with preamp out?

 

[2359glenn]

No but it would come off the EL11 do you want a switch preamp or power amp?
Or do you want to use both at the same time??

 

[UntilThen]

Coming off EL11 is good because it's a good sounding tube.

Probably a switch to either preamp or power amp. Guess I can't listen to both headphones and speakers at the same time.
