Are Stancor replacement transformers still available? I was under the impression they, like so many old time parts manufacturers, were gone with the wind - and we now have only Hammond to choose from.

Ron -

I am an inveterate collector and hoarder of parts. I have a several NOS Stancor and Thordarson universal output transformers, as well as a variety of other vintage iron from those two and other iron manufacturers.

Oh, and your measurement of the Philco speaker voice coils will be good info to look forward to. Please start a separate thread on that topic when you're ready.

Will do. One of the shop improvements is my recently acquired General Radio 1232-A (transistorized) tuned amplifier and null detector. It replaces my old GR 1231-B (tube) amplifier and null detector. The 1232-A is for use with my GR 1210-C (tube) unit R-C oscillator and decades-long favorite GR 1603-A Z-Y bridge. The three together form an all-GR audio impedance measurement system covering 20 Hz to 20 kHz for any audio impedance/admittance from a short circuit to an open circuit. Another part of the shop improvement (not yet completed) is new cabling devoted to that audio impedance/admittance measurement system as well as new pegboard storage for that and other cabling.

I still have to find a place to store the new chassis stand which I recently bought from Simon Sharp. The quality and ruggedness are both superb. It will get its first use soon, and should blow away propping up an inverted chassis at an angle to replace caps.

Another upgrade in the shop overhaul is improved lighting for photographing projects. I needed something more than just the overhead LED replacements for the original fluorescent tubes. I am still working out how to place, mount, and scrim the two new LED lights, and I need a more versatile way to position my DSLR - all I have now is a bracket mounted to a floor joist so the camera is looking down on the bench.
