Hi Folks.
I'm new here. I have just got a hold of an old STC 549 radio console unit and would really appreciate getting a schematic so I can see about getting it up and running. Pretty dusty inside the unit but it looks complete. Here are some images of the unit and internals.
Could also use some service details on voltages if possible.

Appreciate any input here.

Regards,
Fred

PS: Since Brad is having email problems the pics will have to wait for now.

Welcome to steam radio - a great hobby.
Radiomuseum says that this circuit is in 1940/41 AORSM of which I have a copy.
Will scan this tonight and let you when that is done so you can open your email.

Nice one STC380.
Yes, nice to be here and thanks for the assistance.
Look forward to making this thing fire up again.

Circuit is scanned. If you open up your email will send.

Beware that STC circuits in my experience are prone to errors and omissions. For example the circuit for my STC830 shows a voltage divider, but the actual radio shows no signs of ever having had one. I suspect that the discrete resistors that I found instead were a modification that was carried through to the subsequent model the 831. Parts lists can have parts missing, or incorrect values ascribed to parts.

That said a circuit is invaluable. Just don't take it as complete gospel.

Thanks for that.
Not sure how to "open up your email". Is that some setting I need to enable?

There is a setting to open close your email in Control Panel at the top of the page.

That is at the top of the Vintage radio and Television page - not a computer setting.

Things are being disrupted by repeated errors:


500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

OK thanks for that. I have gone into Control Panel and set "Show E-mail Address".
Guessing that's what you mean.
Hope that's right.

Yep you got it right. Email now on the way.

You can reset your email to hidden now if that is what you want.

One other thing ... regarding "You can reset your email to hidden now if that is what you want.".
I'll go with the flow on that. What's the norm?
Is it only visible to members?

I keep mine hidden just as a general security/privacy measure. I think most are hidden. Its up to you.

It is only visible to members but there have been a few flaky members who Brad has turfed out for breaking the rules.
