Questions about Philco 37-611
The power switch on this chassis has multiple positions, can someone explain.
Also the power portion of the one I'm looking at to revive is non operational, is this a common issue,
that can be repaired?
This chassis uses a powered speaker? One that has no permanent magnet and uses a matching transformer ?, what can be used if you do not have the original speaker, at least in the short run to test it.
On the Chassis I have the speaker wires exit the chassis unprotected from the metal and have been damaged by rubbing on the chassis. Was there originally a rubber grommet to protect them?
Is there a owners manual online that covers this chassis. ( I did find the schematic/parts listing)
Before jumping in and replacing caps / resistors I want to evaluate it's current condition.
There are NO previous repairs. It's totally unmolested.
I will test the tubes shortly, once the sw was jumped the chassis drew current not excessive.
And yes, of course it was on an isolated B&K variac through a lamp for safety.
That's where I stopped until I can get at my hickok tester to check the tubes.
Unrelated to the above.
The chassis is destined for a custom cabinet.
I noticed that this chassis has no RF amp, that makes me question it's sensitivity?
Wondered if the cabinet is prepared to accept this chassis is there a superior chassis I could keep an eye out for that will have the same mounting / dial/ knob configuration that could be substituted in the future?
Which brings to mind ,on the 37-611, what would work for an antenna that doesn't require me to run a 20 foot wire out through a wall to a tree? This radio has 3 bands I believe.
