Philco Model 512 Mandarin Red Metal Cone Speaker - Help
#7

Hi Rod,
I am a fan of using a PM Dynamic speaker and an AA5 transformer for these old radios. The weak link as far as fidelity is concerned is the magnetic speaker and the grid leak detector. I have hooked up an RCA 100-a speaker using a transformer in reverse to a hi fi amp and the sound is about as poor as when used on the same vintage radio. There can be many reasons for this including play in the motor, etc, but even in good shape, these speakers do not reproduce music well.

However, for historical accuracy, it is nice to have a working period-correct speaker.

"Do Justly, love Mercy and walk humbly with your God"- Micah 6:8
"Let us begin to do good"- St. Francis

Best Regards,
