[QUOTE="El Sid, post: 854672, member: 18550"] Karel I'm afraid I don't, so I went on a mission off to the interwebs to see what I could find. Here is Mullard's spec for the transformers: [IMG]http://www.r-type.org/articles/art003bx.jpg[/IMG] The Partridge transformers I have are marked D3098, and I can't find anything about them. They don't have UL taps. But (for what it's worth) they [i]look[/i] identical to images of the P3667. I could measure the core for you as well as winding resistance. My R300 multimeter from Mica can't measure L. On this forum I found F_D has similar, which look like mine, even including the yellow varnish: (which model are yours, F_D, and maybe Ampdog can also check the model number?) [IMG]http://i7.photobucket.com/albums/y289/ews2k/Audio/5-10Top.jpg[/IMG] I am interested because I want to build an LSpice model for my amp. [/QUOTE]
