Daughter purchased this rather good performer from a Trash & Treasure sale and it does NOT have the original dial glass which could help identify it.

Its obviously a HMV (Little Nipper maybe??) and the valve line up is 6BE6, Unable to identify, 6AV6, 6M5 & the usual 6X4.

The bottom LH knob is Volume & On/Off, the top LH knob is Tone, The RH top knob is Tuning and below that is WaveChange and PickUp.

Yet the dial shows the Bottom LH being Volume ONLY, the top LH knob being On/Off, the RH Top knob being Tone and the bottom RH knob being Tuning.
No sign of the chassis being extensively modified to support such a major re-hash of the controls.

No ARTS label left to assist either.

It also has a 2 pin 240V output socket on the rear which I will find a way to disconnect.

Any ideas as to model so I can hunt out a circuit?

Perhaps a 64-52.

Don't worry about the socket on the back unless it really bothers you. It's for a turntable and a few radios in the 1950s had these sockets.

The tuning dial is original. These sets were also available under the Kelvinator brand. It should respond well to a chassis overhaul.

The ARTS&P label will be the small type with no prefix letter.

The unable to identify will be a 6BA6.

Yes it is a 64 series.

I found a 64-52 in my collection - it is quite similar to the photo, but not exactly the same. Mine doesn't have any of those sockets on the back, and the 6X4 is further in, with the 6M5 next to the 2nd IF and behind a support structure. Mine also has a ferrite rod antenna - I can't see that in the photo.

The back plastic panel has the holes for the pickup and mains outlet though, even though those things aren't fitted.

Oh, you said yours has a wavechange switch for shortwave? The 64-52 is medium-wave only.

I forgot to point out that the Kelvinator branded version of this radio was my first ever radio, purchased for $3.00 at Munro's Mill Antique Centre in Tamworth.

I have a wreck here with the plug for the turntable someone has butchered it & added SW I have a HMV series 42 chassis on the bench which has a different layout & no markings & is out of a mint Bakelite cabinet.

It had no ID however, think this out. If you get the parts list, it, in the case of the one here, I got onto via Kevin chant site and found the chassis layout. As most of these sets have a date on them the fixer "3-53". So in not much time I found 41-72. Note it has a roll cage,

I now find it should have three 10K parallel 10K resistors as a B+ dropper /choke & its only got two? Which reminds me in those others the early sets had 2 x 22K in parallel for the RF screens & with likely interference from the bean counters, this became10K? If that is1Watt it will burn & often does. Current squared by resistance = 10mA and max screen current is around 18mA depending on the B voltage: Oops.

Also check the numbers on IF cans & transformers the wreck PT is 9040001 chassis 42 is 9040004 That tends to appear on the parts list that info helps ID it.

Waveband switch on 42 is a 5 position viz. Gram, MW, SW1, SW2, SW3, dial is 7940191 104.1mm by 245mm; Whist the wreck is 7940201; 68.9mm by 103mm not the same as photo as wreck has only on / off/ vol & tuning. Both actual dimensions , out of cabinet.

I will look at Kevin Chant site might be chassis 31?

I think it may be a Model 34-52.

https://www.kevinchant.com/uploads/7/1/0/8/7108231/chassis_type_34_and_new_type_34.pdf

One possible explanation for the rehash of the controls is that the chassis is a 35 type as used in the Nippergrams.

https://www.kevinchant.com/uploads/7/1/0/8/7108231/chassis_type_35.pdf

Just a theory.

Yeah, I'd agree with that guess. That type-34 schematic has an "old type" and a "new type" - the photo clearly identifies it as an "old type".

My guess is that the original case or dial got broken, and someone substituted a case from a 64-52, hoping that nobody would notice the different placement of the controls.

Just another theory. Grin

Thanks fellas...great lot of info supplied.

Will have a look at Kevin Chants site and see what I can match up.

Quite possible the chassis is from a Nippergram and setup in a mantel case as suggested.

It is definitely a 2 Band set (MW/SW bands and Pickup switching on the same knob.

NO Ferrite antenna in this one...just a wire trailing out of the grommet which looks original.

The chassis has been worked on with most caps replaced and a few odd resistors and it goes really well.

Where it is going to be domiciled there are at least 3 AM stations so daughter is quite happy and the intention is to use the PU function to allow her iPhone to be plugged in so she can stream her music through it...An isolating transformer with the L & R out of the iPhone commoned through a couple of 10K resistors and the applicable lead to plug into her iPhone.

An Update: After downloading the info from Kevin Chant it is most definitely a type 35 Chassis so we now have the correct info which is great for future reference.

You could always connect a (cheap) bluetooth receiver into the input terminals and power it via the 2-pin 240 volt mains socket. That way the music and volume can be controlled anywhere in the room or even the house by the iPhone.

I currently have this set up at home with a valve radio and an old retired iPhone (no SIM card and on flight mode) connected to the home wi-fi.

With Spotify, Youtube music and various radio apps I can pretty much listen to anything I like.

I've done several Bluetooth conversions recently.
$5 Chinese receiver, voltage doubler circuit straight off 6.3 volt filament line, into lm7805 regulator.
In all cases wired in such a way that easy removal without trace is possible.
Large consoles with Bluetooth receiver becoming very popular, due to "bass" and "valve sound".
Not my quote.

For info I posted 42-71 on my Facebook page https://www.facebook.com/marcus.chick.940 that will show the likely dial style for one with SW
