I did manage to get the sheet showing the stringing of the "Condenser drive", "Pointer drive", and the Wave change guide, but no info on model and none is evident. Its had a hard life. I was told it worked, by the old chap (93) as he had recently worked on it & tested all of the caps (that are now in my bin), so how he did that will remain a mystery. He was going to send info on it, but took sick & died about a fortnight later.

I have sent Brad photos. That will show valve compliment, European numbers. Two KTW61M, Y61, X61M, U52, DH63M, KT66.

Its had a hard life the octal speaker is actually holed.

Marc,

I have a 21 page service manual for a Model 5300 radiogram with that valve line-up.

This was an UK export model sold in Australia during 1948 & 1949. There may well be also a console & table model version using the same chassis.

Eagerly awaiting the snaps.

Update: A table model with the same valve line-up, 5101, was also sold in Australia during the same period. Unfortunately no service manual on hand.

It would be interesting to see if the HMV export models sold in Australia had long-wave.

Did not take a photo of the front of the chassis however there are 5 shafts. The wave change dial goes 13m, 16m, 19m, 25m, 31m, SW, MW, LW. So its got aircraft beacons.

Tried to download 5101 from radio museum but that seems to have failed; always have issues with it.

Cabinet looks the same.

The 5101 looks almost identical to the 7101 I linked to in post #2.

Is that the mantel that you have?

7101 has a different cabinet Mine has the 5101 cabinet, its unlikely that the chassis is different

Yeah, I meant to type almost identical. Same schematic applies to both -- I have emailed it to you.

Yeah! I think we both new what we meant. However, I see the circuit has appeared for which I am most grateful: Thanks.

You will note its condition from the photos. The old guy (93) as noted, had to get rid of his stuff (how often that happens) in a hurry as his wife was at the point of palliative care, so they had chosen to dispose of the house & move into adjacent rooms, in a home for the terminally bewildered where she could be looked after and they could still be together. A wonderful plan, but one that was sadly not to be.

As the radio club is basically in limbo I did write up a bit about it in the Radio Clubs mag as padding, set is still a work in progress . Save to say after the chassis failed visual inspection, it never got powered as the mains cable was but one of the dodgy wires that got binned. most of the knobs a cactus.

The scary part was the caps. The filters are new, but that's where the good news ended. He said he tested the caps?? Original wax papers & other electrolytic caps still in there: How did he do that? I tested one NP where an end had fallen off? I have not identified from where, in the circuit but it was a dud & there's a new one tacked in waiting for me to look on the circuit and sort it.

Speakers got a hole in its cone & as I tossed all of the caps I found seven dry joints.

How did it run?

How did it run?

Given the age of the owner and his circumstances, he'd probably forgotten when it last worked. My late father in law was very skilled with his hands, however, as he got older he thought he was fixing stuff but the sad fact is that he wasn't. Nobody had the heart to tell him though.

The fact it was in two pieces, like chassis on the bench and he said he had been working on it, was the scary bit. Rule number one here is, check anything mains powered where you do not know its history, or you are suspicious of it. With the chassis already out, problems were already obvious. So one accepted it with an appreciation & tact & dumped it's already separated chassis, on their bench.

I have had another incident like that: I came back from a clearing sale with a BWD dual trace CRO Oscilloscope and some radios from a collector that were supposed to work seller was in his late 80's & died recently at age 99.

The first one failed inspection as when we took the back off we were greeted by a lonely cap, which had also fallen off?

Over close to five decades I have seen some incredible & deadly things done to radios.

Photos uploaded.

Brad, Thanks for posting pics.

You will note the tube in the same grey colour as the Nazi ones, not the later red Philips "Metalisation" that we are familiar with.

That flaking "Metalisation" can be replaced using conductive glue and a binder to cover it. There is also a temptation to add some of the kids glitter to it. (Got the glitter not the rug rats).

I have patched the speaker cone. Damage was done from the back of it, interesting was a dot of green colour, next to the hole? Not related to the green I used as I checked the terminations.

Speaker plug is missing a pin & needs some TLC, however, the construction says that I can turn a new one, from brass (have in stock).
