Audiomaster Type 11A & W&N/520 amplifier

Posted by john_keung (A) on October 9, 2007 at 08:17:41

Hi all

I just acquired a pair of Audiomaster Type 11A amplifiers. When I
checked with HiFi Year Book 1959, I saw W&N/520 which looks exact my
Type 11A amplifier. Is there any difference between them?

My pair of 11A came with Haddon transformers / choke which is the
same brandname of transformers used in Leak TL/12 Point One. I also
found that there is another version of 11A which came with Partridge
transformers.

Any comment on the Haddon / Partridge type 11A amplifier??
