WTB 3.5-5K - 8ohm single ended output transformers

[deicide67]

Just as title says. Edcor, one electron, etc.

I know I can order direct, but Edcor lead times suck and I know there are probably a few of you with some in the parts bin.

Thanks!

What wattage would be needed for these transformers?
What output tubes would they be used with?
There are a number of reputable suppliers online, such as Triode Electronics, etc.

Thank you. I’m aware of most, if not all US based distributors. Output tubes don’t really matter. I’m looking for 3.5-5K primary with 8 ohm secondaries. 8-10W.

My last amp was 6829 into 6DN6 for output valves, so that’s why the valves aren’t important to list.

I have a pair of Magnequest RH-60 transformers that I don't have plans for just yet.

Still looking. Thanks!

Triode Electronics online has an extensive list of in-stock transformers.

I have used toroidy SE transformers in a pair of experimental amps using 6s4s and 6p15p ~4W with good results, expected lots of rolloff, but they beat very well into 30 hz and up to 15 khz with no visible signs of core saturation their catalogue is fair between 600ohm (6S33S, 6AS7) and up to 7K for GM70 based proyects.

Thank you. If you look at and read the post, your response is a little redundant.

These are tough to get in the US. Plus, shipping would take about as long as Edcor.

I’ve wanted to try these though.

Indeed, but have you looked at their offerings?

 

[deicide67]

Yes,

I have a pair of their 30W outputs here at the house.

I have a pair of TM 3KB. Can't remember if they are 3 or 3.5k. These were used as prototype and the tags on they secondaries have fallen off. there are 4 secondary windings. You need to uses your scope to deterimine each one.

$150 plus shipping
