vt4c output transformer

Does anybody have any experience with this transformer: MARS LM-2017U.
This is a very cheap 3.5K output transformer for 300B, but I dont know what to expect of them.

Can anybody help me?

Regards

Sorry my English is not to good.
 
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 haven´t started to build yet) but I listened to the transformers in a E280F quarter-watt spud amp and they didn´t 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.
