For Sale Power Transformers (Monolith and Hammond)

[galibier_man]

All 8 transformers for $375 (shipping to CONUS included)​

These transformers were used during amplifier prototyping.

Because we were experimenting with various filament voltages, we spec'd these Monolith Power Transformers for two B+ secondaries (375-0-375 and 275-0-275) with no filament windings.

We have been running current hungry damper diodes (4 of them), with each one drawing 1.8A, and hence that 12A filament transformer.

Here are the details:

• 1 pair Monolith Power transformers: 120V primary, dual B+ (275-0-275 & 375-0-375)
• 1 pair Hammond 167L12: 12.6V/2.5A
• 1 pair Hammond 167T6: 6.3V/12A
• 1 pair Hammond 167N6: 6.3V/4A

The leads on the Monoliths are all original length (about 11"). The center taps on the filament transformers were snipped and the leads are various lengths.

Thanks for looking (scroll down),

I forgot to specify the current on the Monolith power trannies.

The 750V secondary is spec'd at 155mA and the 550V is 75mA.

Yves (@ Monolith) designs headroom into his designs and requests that you don't "over" spec them. It's something he does during the design process

Attached is the design sheet.

The trannies have a new home. Cleaning house further (and a bit lower on the food chain), I have quite a few Hammond PTs I'll be putting up. They'll be $25 each and $40 for a pair (plus shipping). Stay tuned ...
