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.

If it's a portable/tablegram, then it could be a Kriesler 11-92 of 1962 (6AN7 6N8 6BM8 6BM8 6V4)

Schematic here: http://www.kevinchant.com/uploads/7/1/0/8/7108231/11-92.pdf

If floor-standing, then it could be a Philips 223 of 1960 (6AN7 6N8 6BM8 6BM8 6V4)

Schematic here: http://www.kevinchant.com/uploads/7/1/0/8/7108231/223.pdf

A 7 pin pentagrid would most likely be a 6BE6.

Also it is mentioned that it has short-wave.

So a likely candidate could be this:

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.
