Hi all, the writer is suffering from brain-fade and need a chassis identified if possible.
A prospective client brought this radiogram in to me for repair in the 80's !!!! The cabinet was very dilapidated and tied up with string and tape so was "past it" the gram mech was missing, dial scale missing and speakers were corroded and cones ripped out, so everything was dumped except the chassis.
My attitude: another chassis "saved"....
As per normal, I think the "client" wanted to simply dump it at my workshop instead of going to the tip !!! or just abandon...which all service techs suffered from this problem....of filling up the workshop...with unwanted goods...so the "client can go to "Colesworth" in next BIG city to buy a new one.!
Appears to be Kriesler or HMV, last of the "valve era"
Valve lineup is miniature 7 pin pentagrid for RF/mixer (number obliterated) 6N8, 2 off 6BM8, & 6V4.
2 gang tuning cap, 2 IFT's, stereo, s/n on chassis: 034802. Arts&p label obliterated, but can see letter A and part of 2nd character which looks like a O or C or Q...!!
Needs output transformer(s) otherwise looks fairly good and not butchered underneath the chassis.
Controls from Left: SW-MW-Gram function switch, Tune, Bal, Vol, Tone/on-off.

The pentagrid is a 6BE6, as soon as I read monochromeTV's post, the ol brain unfaded that cell...!! Ok on being a Precedent, here is me thinking it may have been a Kriesler, going by the heavy die-cast knobs..!!!
The schematic is correct, -761, with the SW band.
Now can repair the chassis but have no cabinet for it..
Cheers and thanks all round.

Just wondering whether anyone who posted on this thread is still around? I have just acquired an Airlord (Australian) radiogram with the same chassis.

Verry much the dogs dinner underneath. Those scruffy, funny looking yellow things look like sealed oil filled caps. If so they are as bad, or worse than the paper type caps and should be tossed out.

Not his chassis Marc. Post is 8 years old.
They are resistors. Pink caps are polyester Anocaps. Untidiest Precedent chassis I've ever seen!

Yes, not my chassis! I have the same chassis inside an Airlord Radiogram - I've just started a new thread on it on this forum.

So, one would expect it too, to present as "Rats Nest" wiring at its best?. And you wonder why some sets have problems.
Badge engineering has never gone away. Still have a 1936 Car Radio here, it was built by Astor, but is in "Rider" (USA) under Philco Radio & Television Corp. As C-1452 Chrysler.

Precedent point to point wiring was normally very tidy.

Perhaps a special Friday rush delivery order before a holiday job. That's the explanation I see for a radio that turned up here, with obvious signs of work, but no output.
Dead heater on 6V6. However, it needed a birthday and in my doing of that I notice that pin 7 on the 6V6 socket, had never been soldered. On powering with the same 6V6, heaters and radio noise. The question then becomes; "How the hell, did that get missed by several?"
