Post subject:  Toroidal Transformers & Capacitors

I realize that with the general lean towards tubes most of this stuff will be of no interest to you, but I figured I'd give it a shot. Not looking for a lot of money, make me a half way reasonable offer and we can move junk from my house to yours.

Quantity two - 2.5 kVA toroidal transformers, they provide +/- 81 VDC, 120/240 VAC primaries. One is mounted on a chassis with two bridge rectifiers and four 51,000 uF caps. The other is not mounted, but I do have four more caps and two bridge rectifiers.

Quantity 1 - 3 kVA isolation transformer, toroidal, primary 0/100/120, secondary 0/120

I also have several 1.6 kVA transformers with dual secondaries

Something that may be of interest to those concerned with noise on the AC power, I have a number of new TCI KDRF2HC3 drive reactor filters. These are new. They are used to filter noise generated by variable frequency motor drives from going back into the AC supply. Cheap. Here's a link: https://transcoil.com/product/kdrf2hc3/

Quantity 5 - 110,000 uF 16 VDC electrolytic caps, Mallory
Quantity 5 - 50,000 uF 25 Volt electrolytic caps, Sprague Powerlytic
Quantity 8 - 33,000 uF 50 Volt electrolytic caps, Mitsubishi?
Quantity 8 - 25,000 uF 16 VDC electrolytic caps, Mallory

Approximately 3,000 - 3.3 uF 16 Volt tantalum caps
Approximately 500 - .33 uF 50 Volt tantalum caps
Quantity 500 - .033 uF 100 Volt polyester caps, bag of 500, Myung Sung Electronics
Quantity 500 - .033 uF 50 Volt stacked metalized polyester caps (pretty sure), Panasonic type ECQ-V, bags of 100

Quantity thousands - 1N914 diode
Quantity thousands - 1N4007 diode

Quantity 200+ - 7812+12 Volt voltage regulator

Let me know if you have any interest in anything.

Dave

I need one 1n007 diode

Too bad he only has 1N4007 diodes. :crazy:

I'll take care of your needs. At least for one 1N4007 diode.

I can only imagine what each 2.5K toroid weighs and I wonder how much heat would be produced by a Pass design amp built using such a transformer.

It also raises the issue of all the 'stuff' that we collect over time. I am back to packing most of my stuff for the move to Australia and am pondering what I too will be trying to get rid of in the next few months. I will bring some to a future meet to give away because otherwise it will go to the dump.
