    Recording SVT output transformer comparo...stock vs. Heyboer

    So yesterday I got a second Heritage SVT rig: Yeah, I know. The new one is bone stock while the old one from 2013 has a Heyboer output transformer spec'd on an original Blue Line transformer. I got the Heyboer after a couple discussions on here and some consultations with Ampeg employees...

    Eden WTDI transformer picks up line noise

    The WTDI is a great little preamp (even if it's a one trick pony, it's a great trick) but the 15 volt 400 miliamp center positive tranformer is a weirdo and is picking up line noise when my wife sews (I think it's the iron being plugged in). She sews a lot, is a published quilter, so I'm often...

    Fun with transformers

    I have a power transformer with a B+(330-0-330) that has a 56v tap on one winding. So it's 330,0,56,330, 0 being CT. if I use only the one winding on one side of CT and the 56v bias tap, will this hurt the tray in some way? To clarify, I'd be using it like 330-0-56 with CT to ground. I'm doing...

    Amp transformer replacment?

    Hey gang, I'm asking for a friend because I know someone here should know a ballpark figure. My buddy has an old Marshall jcm 900. His tech said the transformer is shot and while the part is about $90 the work would run into the hundreds , and wouldn't tell him an approximate cost. I know I...

    Just the transformer for the Cali76 TX

    I've listened to several demos of the Cali76 TX, the one with the iron core transformer, and I've decided that I like what it does very much. However, I'd like to have that sound independent of the compressor. Is there anything out there that does the same sort of thing to the sound coming out...

    Output Transformer in my 300T blew :(

    Hey guys, So sadly the output transformer in my Sunn 300T blew the other night. I've searched all over to find a replacement for it and have had little luck. Since the Fender Bassman 300 pro is the same thing I tried looking for it with that as the key words in a few search engines as well...

    I have a Demeter HBP-1 and I am trying to figure out if it has a Jensen mod. It says Jensen on the back panel, but I cannot see anything marked Jensen inside. Does any one have a picture of the Jensen in a HBP-1? Thanks

    Hey so I'm planning on building my own Ampeg B-15 shameless copy.

I was wondering if...
