    What kind of Western Electric transformers are these?

    Anyone able to tell me what kind of transformers are these? I'm not too sure I can decipher this data sheet much. =AZUbpBePNv3_ZRBD6CoQPAKhxb0epvHek79ksdU_UyKlWXNTLyJI97Cqz4q085kZaQVzu5fZu449KADm3Zk6fm56G5oraCJeOJ1yebQ3yoKigINFn_iBnC1zjfHmwclUsO6dO-FgA8OfZDDftQGwZY5M&__tn__=*bH-R']...

    Help finding data on vintage Peerless Transformers

    Hello, First post here, but regular reader ;) i got a set of 2 x input and 2 x output transformers that i pulled from a working Westrex cinema PA tube amp ( it was impossible to keep it and restore it... ). They seem to be Peerless / Altec Lansing corp. Transformers, with references : T-101...

    A few more DIY Tube amp Questions

    After a bit of pondering after my last post, I've got two designs in mind. I'd prefer not to spend the $250 on a pair of ST-70 output transformers. I'd like to keep the output transformers under 200. I'm trying to decide between building an "ST-70" with Edcor transformers (probably have to be a...

    Modeling transformers in LTspice

    Recently, I've been learning how to model transformers in LTspice, and today I decided to make a SUBCKT for the Heath 54-89 (the power transformer for the AA-100). It seems to work fine. Attached, in case anyone is interested. The LTspice tutorial is pretty clear on how to do this, and so I...

    Luxman CL-35 MKIII MC transformers

    I'm interested in using the moving coil phono stage on my Luxman CL-35 MKiii preamp for my Denon 103S & 301ii cartridges but I do not have the transformers for the 9pin sockets on the rear. Is there a replacement of any kind for the 6400 series transformers mentioned in the manual? (3rd photo...

    Sansui AU-X1 transformer T702/4002970 wanted

    Hello, I am (with help from a service shop) restoring a Sansui AU-X1 integrated amp, and have found that the transformer referred to as T702 in the service manual, model no 4002970 needs to be replaced. (The one in the unit says 4002971, by the way, not sure why.) Any ideas where to get this...

    Odd Output Transformer Needed

    I got a crazy idea to build this little headphone amplifier from a 1960 something magazine article that I stumbled upon (attached). Problem is, I have now rounded up nearly all the parts except the elusive output transformers! The article says I could use a Triad S-13 X. There is nothing special...

    To ship or not to ship.....

    Moved from Australia to Texas last year and will be shipping some household stuff to our new home soon, so have to decide whether to ship my amps and CD/DAC to the states and use a step up transformer or buy new here. Will ship my speakers, and would like to hear from anyone who has had...

    Straange triodes

    I'm still working on my PPP triode amp using 6AS7s. From what I read in the little information available on these workhorses I thought I should be able to count on a really clean 20+ W. I'm getting about 15. I wouldn't worry about 5 watts if I was building KT88s but a loss of 25% with the...
