Tube transformers for sale

Years ago I wanted to build a tube amplifier, but lost interest over the years. I have a bunch of transformers I purchased for several projects that I'm looking to offload to someone in Europe for a great price. Most of them came from this site: https://www.ogonowski.eu/

If anyone is interested, drop me a line and I'll put a list together. In the box next to me I have:

1. Power transformer 180W --1pcs

2. Output transformer PP40-G1 --1pcs

3. Output transformer SE25-5 --2pcs

From that site. Those are for a Push/Pull amplifier I think, but I also have some for a single ended I was working on as well.

I'm based in Spain, so these will have to stay in Europe due to cost reasons (they all weigh a lot, so shipping won't be super cheap I don't think).
 
The SE25-5s have never even been opened - I had this box sitting here since COVID, and it's just been in the way.

I also have the following that I started to mount for a project, but gave up as well.

1. 2x Transformers PP80-1 (laminations annealed 0,3mm) Raa=6k/4 and 8 Ohm UL 43%

2. Transformer TS400 (laminations annealed 0,3mm)

Primary Winding: 0-115V, 0-115V (so it can be used at 230V or 115V)
For 230V connect in series two primary windings and for 115V connect in parallel two primary windings.
Secondary Windings:
a) 350V-0V-350V 0.35A
b) 6.3V, 5A
c) 6.3V, 5A
d) 6.3V, 3.0A
Output voltages will be on the pins.

3. Choke D10-1 (laminations annealed 0,3mm) I think (I can look for sure when I take it apart).
