An AM/FM prewar set, this one by Emerson.
Caution, screwheads on bottom of cabinet of the
578A are directly connected to the powerline!
This FM tuner uses octal tubes! Model XFM-1
The GE model 1284A set above needed its high voltage audio output transistor replaced. Used an NPN bipolar transistor from the switching power supply of a junked monochrome monitor to replace it, worked fine. If you have a GE radio like this one that is dead, check the output transistor. I've had several with bad output transistors.
This GE C1580Z is the 1284A with clock.
The homebrew set below uses GE circuit boards
almost identical to those in the GE T1290A and T1290 sets above.
Here I installed a powerline RFI filter behind the speaker Radio now almost seems like a portable on batteries.
This homebrew set above uses a GE circuit board almost identical to that in the GE T1290A. Right click "view image" to see the schematic, with my mods, full size. These mods include a separate AM detector using a base-collector strapped transistor for better weak signal demodulation, an RFI filter on the incoming powerline, and changing a grounded (with respect to RF) base bipolar transistor to a grounded gate JFET in the FM RF amp stage; this is to improve the RF stage to have good strong signal performance, ie, better FM receive dynamic range, ie, a better intercept point. avoiding intermod products. You'd want this if you live near New York City, with its crowded FM dial, right.

Meissner 9-1047A tuner for the old 45MHz FM band.
This T601 has FM channel numbers, most don't.

A European tube import
.. A Steelman 4AR12 console set, AM and phono:
This Truetone is virtually identical to my brother's Lafayette set.
A nice tube radio with extra B+ on the audio output stage:
The H458T6 is just like this except brown trim instead of black around the front. See below. Using a 19HR6 tube in place of the 12BA6 in the IF amp stage improves the sensitivity of this set. This radio may be easily converted to 240VAC operation by removing the powerline (mains) connection from the center of the autotransformer to the top (rectifier plate). Leave the heater string connected to the center tap. See the diagram here.
This below Zenith had its selenium rectifier replaced by a silicon bridge. Details here.
