3 Tube Amp HV Power Transformers (Triad, Edcor)
Price drop $130 plus shipping for all Three!
I'm selling more of my tube components just collecting dust. These are NOS transformers. What I have is a pair of Triad R-108A power transformers and an Edcor XPWR074: https://www.edcorusa.com/xpwr074
I was intending on eventually using the Triads to build a pair of 45 (DHT SET) `mono-blocs. At 70ma DC and 500VCT they might be used for a pair of
2A3 amps provided you went with silicon rectification and biased below the standard 60ma level. It seems Jeff Medwin suggested the mid 40's as a nice sounding operating point a few years back from my notes.
You can see the images below for the specs, but they have a 2 amp 5V and 2.5A 6.3 volt secondaries and have a electrostatic shield for low radiated EMI.
I was considering the Edcor for one of Bruce Heran's SIPP designs.
The Triad transformers have some scratches on the back from someone setting them in the box with the wires underneath them before shipping them to me (and there's plenty of room in the box otherwise...arrgghH). So they're not perfect, but still really nice and the scratches are only on the backs. I did my best to show them in the images.
I'd like to sell all three for $130 plus shipping. they will fit in a USPS flat rate box, so shipping will be 13.00 to the CONUS (Shipping is only to the CONUS my apologies to DIYer's elsewhere).
The Edcor is a standard Blue color transformer. I didn't include images since they're a new stock unit. I can take some images of the Edcors if so desired.
Thanks for looking at my Ad!
