Up for sale here is this vintage Eico AF-4 tube amplifier. This is in good shape, but does have light to moderate overall wear. One knob is incorrect (the back level control), and it is missing the rear jack that was used for the speakers--it has three wires coming out--one for left positive, one for right positive, and one for both channel negatives. This normally uses one 6CA4 tube, two 7247 tubes, and two EL84 output tubes, but those are not included. This is complete other than tubes (and the screws that hold on the top screen are missing as well).
I tested this (using some tubes I had laying around, which are not included) and it played on both channels, but had a little bit of a background hum. The volume control seemed uneven at lower levels, but even at higher levels, though that could be related to the tubes I was using or any number of other things.
This looks original, and the wiring looks pretty good to me, so it shouldn't be too hard to restore.
Because this is a vintage tube amplifier, it needs to be restored and is not safe for regular use. This is sold as non-working, for restoration. Once restored, this will be an incredible amplifier. Please see my pictures for details.
US shipping and handling is $25, and international is $120. If you have any questions, please ask.
I have more tube gear and other vintage electronics listed--feel free to take a look!
