Clipper Radiogram (model 7G4) Repair

Old footage I found, that I thought I had lost. Camera work is a bit off, audio is a lot off... but its a repair I did around 3 years ago when I knew even less about making TH-cam videos than I do now - and I know almost nothing presently, so it was pretty bad. At the end I also explain how to use an old record player for those who don't know.

Apologies for the terrible audio - this was before I got a half-decent microphone. You may need to turn this one up a little - or just pass it by 😂

You're welcome John!

I have one of those wire-strippers, like you I've had it years. I call it the 'Ker-plunker' because of the noise it makes! (I call it something else if I catch my fingers, though).

[@VintageRadioSteve]

🤣 Thats a great name for them...

The Original 78 rpm turntable was changed out for the 1960's BSR at some point.

[@VintageRadioSteve]

According to the advertising I have it was either fitted with a Garrard RC110 3-speed changer, or a BSR Morarch changer, from the factory (no doubt dependent on what they could get at the time) - so I don't think this one would have ever just had a 78 player. I believe this particular Monarch player was mid-50's so it would be around the right era. Cheers, Steve

Nice work. That 270 ohm resistor for feedback.... what about a potentiometer of lets say 470 ohm to adjust compensation for wear on the tube. (One day there will only be limited number of tubes available).

[@VintageRadioSteve]

Cheers, and that could be an interesting experiment. I'm not sure what effect that would have though - I don't think the problem is wear on the valve, I think it's an internal fault. The other valve probably never had its diodes used being in the phase inverter position, but still seemed to have a slight audio leak. I don't recall checking the 270 ohm resistor - it could have gone high possibly...

A radio tech told me that the BSR turntables are the easiest to service.

[@VintageRadioSteve]

Cheers, I find them all works of black magic... but pretty much all kiwi radiograms either had BSR or Garrard turntables - there were exceptions of course, but those two make up the vast majority. Philips would probably come third...

and now to take the played record off ;-)

[@VintageRadioSteve]

Simple, just break the record in half, and slide each half out... 😂
