Basement cleanout. All offers considered.

I'm sorting through my stuff and offering the items here. Most of what I kept was for DIY audio projects. I'll post new items as I come across them. Unfortunatly, I can't edit my posts for long so you may need to look through the entire thread to find something you might want.

If a mod is listening is there a way you can allow me to edit this post indefinitely?

Here's the first of many large power transformers. It would be great for a DIY transistorized amplifier. Lot of taps suit many design requirements. It was from a 200w reciever.

Here are the approximate OC (open circuit) voltages.

120v primary (thermally protected)
42-0-42 secondary (fairly heavy gauge winding)
16.3-11-0-11-16.3 secondary
5.8v secondary

Next up. A power amp on a board. 2-channel. 2SD370+2SB530 outputs. Preamp board, regulator, power transformer, and outputs on a 4x TO-3 heatsink. Condition unknown. Looks like it may have a blown channel judging by 2 burnt 100ohm resistors on the preamp board. Inputs/power/outputs conveniently labled on the silkscreen.

Will seperate.

2 Foster dome/horn tweeter 49-1168. (Manufactured for Zenith) With crossovers. Also 2 CTS cup midranges. I remember these mids.

2 B&W BZ200 8" woofers. From '85. Doesn't take much to drive these. Rubber surround intact. Also 2 DM110 crossovers and one B&W dome tweeter (someone need a replacement?).

2 7.5w mini monoblocks. Don't underestimate these little guys. They can easily drive efficient speakers. 9-12vdc. On-board regulator.

Red: B+
Blue: Input
Black: Ground
Small Blue: Speaker +
Small white: Speaker -

I may be interested in the B&W gear. I am also in Chicago (Naperville)...let me know what your asking price is...

I'm up north at the Wi. border more or less. Just shoot me an offer. I need stuff cleared out. I'll trade for tube amp parts if you have anything kicking around. :)

I have a number of tubes - tons of them. I have mullard 12AT6, and 6BM8 that are favorites around here.

6922, 7N7, 7F7, PL84, 6Y6, a quad of Ruby 6L6GC, quad of Electro Harmonix EL34 (1 may be bad), and quite a few more...

I might be interested in your 6L6GC set. New or used? Maybe the 6Y6 also but it's a bit of an oddball. The guitar guys sometimes swap them in place of 6V6s. The 12AY6 is a single triode right? Do you have any chassis or transformers?

On another note. Here's some more power transformers to put on the parts table. They are 120v primary with a 14v center tapped 250ma secondary. Made by Stancore #P8577. Good small transformer for SS preamp? New in box. I have 3. 1 has no box. The primary has 4 wires and I'm not sure if it's 2 120v windings or something different. IF it's 2 SEPERATE windings, one could be used for HV supply but the tube must use a low current heater. Being rated at 14v you could manage a 12v DC heater supply. A little head room for the diodes' voltage drops.

EDIT - There are indeed 2 seperate 120v windings. These could be used for a tube preamp's HV and heater supply.
