Eico HF20 Power and Output Transformers FS

Doug R · 21st October 2010, 06:37 PM

I took these out of a working Eico HF20 6L6 push-pull mono amp. I don't have time to finish all my projects, so I would like to pass these along so someone can use them.

The power transformer weighs 5 pounds 7 ounces.
The potted output transformer is Ginormous! It weighs 13.5 pounds! In the photo below, there is a red Hammond 272X for comparison.

Asking $60 for both, plus shipping (which won't be cheap - weight will be about 21 pounds.)

I'm iterested. Drop me a PM if you want. Will they fit in a USPS flat rate box...if so weight will not mater. I ship a lot of xfrms that way. Trades? See my post.

Yes they will! Hooray. That will keep the shipping cost down to $10.70.

Do you know the secondary volts and amps on the power xfrm?

Doug R · 22nd October 2010, 03:46 PM

From the schematic, 740 volts
2.4 A at 6.3V
3.0 A at 5V
The amp was rated at 20W, but I would imagine the transformers were just coasting at that wattage.

I had a copy of the circuit but not the PS. I was looking for a xfrm to build a AX84 guitar amp, so I will pass on the PS xfrm, but still interested in the output.

I'm intrested in the op transformer

I am going to list them on ebay. Thanks.
