I am wanting to build a tube amp and the most expensive part of my amp is the audio transformers?

I have a lead one 1k and 2k primaries. What type of SE amp could be built? Could it be used for a parallel SE amp?

Any suggestions?

Unless you are doing something unusual, yeah, transformers make up a large cost of a tube amp.

Do you have output transformers already? Do you have a pair? Does the pair have a primary impedance of 1K or 2K?

Just trying to sort out your somewhat confusing post.

If the transformers can handle the primary current without loosing their inductance, then 6GB5/EL509/17GB5/PL509.

@Bricktop: Do you have any schematics that I could see?

These transformers are 3-5 watt only would that be okay?

Perhaps a 6AS7/6080?

I believe AK user Kegger has built an amp that uses 6GB5s, though I'm not sure if his schematic is posted somewhere. Try searching the Tube and DIY forum and if you can't find one, PM Kegger.

Here is the thread..

I used basically a 2.5k primary. (2k would work)

The 8608 is not as easily available for driver, the 6DJ8 mod
down farther would be much easier an cheaper to come by.
