Can anybody help me?

Sorry, I don't have experience of these. I was interested too, so had a look for myself.
Certainly the price looks good, but sometimes the shipping costs are high.

Just posted the link so more people might look.

A friend built Mikael's SE KT88 using Mars OPT, according to him it sounds gorgeous.

I have not heard his amp, he lives in New Zealand, but I trust his judgement, he is into vintage Sansuis and I think he knows his audio quite well.

I have a pair of those transformers, I bought them off Ebay rather than from vt4c.com but they look exactly identical and have the same specs.
I bought them for an RCA 808 SE project (which I havenīt started to build yet) but I listened to the transformers in a E280F quarter-watt spud amp and they didnīt sound half bad.
Thinking about ditching those silly 808s and use the transformers as 1,75k/8 OPTs together with triode wired 40KG6 instead, should give about 12W.

Mars Transformers
 
Hello,
I have bought several transformers from Mars, VT4C one power transformer and a couple pairs of output transformers. They seem well built and sound great to my not so trained ears on this amp using 2A3 output tubes and Klipsch RB-61 speakers. This set uses the 2.5K output transformers, but the 3.5 K are similar. I have also purchased their circular drill bits for making the holes in the panel for the tube sockets and they work great and give a very clean hole.
