i have one of those, although pretty sure innards of mine are very different and look much newer although still discrete transistor! plus have a similar style 'repro' of the philips 634A 'ovaltiney' set i think dating from the 70s or 80s, there was at least 2 versions of the philips, one with innards from a far east made portable, (i have one of the portables that use that board), adapted to this cabinet, plus another variant with 'unique' innards using an IC(the other was all discrete transistor, even having germanium outputs), both actually seem to be made by philips or one of their related companies, not one of the later 1990s chinese 'repro's
from what I've found out so far the set I have is basically the same circuit as used in one of the Phillips branded sets but made in Roumania using eastern Europe manufactured components
The plastics had no chance vs the seized radio volume switch. I wonder is this common? My radios air variable capacitor shaft had seized up. Isoprop loosened it up, but not long after it would seize again. The only advice I can think of is to use zip tie on the broken end of the knob to keep it from splitting up again. Intereting stuff!
Yes very common indeed, especially with eastern European stuff. IPA will only loosen it for a short time like you found out. the trick is to use IPA then a very light grease. it also helps if you can warm the part up a little first to allow the grease to flow in. for the broken knob I'll make a sleeve to go over the broken section and glue it in place.
A lot of the Eastern European stuff has a Philips look to it and looking st that board it does have a Philips look to it. The firm Electronica in Romania was set up by Philips but I don't see this model although there is one that looks similar-ish. The boards do have a problem with cracks in them and the transistors do fail. The speakers have some funny habits on these as well....
Someone has sent me a link to the service data and yes basically its a Phillips circuit. I will have to inspect the PCB for bad solder joints some look quite suspect.
I cant actually post the link hear due to youtube stupidity, however i'll put the link in the description of the next video on the set which will be up in a day or so as I have made some progress.
@@Jayoldstuff1 the model no. of my philips 'ovaltiney' discrete transistor repro is 13R634/15Z, the other variant with IC is i think 22RB634 but not sure, was it one of these? may of course be other models similar.....
Yea RUclips has got silly with links now. Can you send the links in an email to jasontaylorelectric@gmail.com and many thanks any help with this one is most appreciated
that is not a radio, its more like a reception device, it wouldn't do any noise unless you would connect it to an antenna type of cable that would transmit the signal
Romania wasn't part of the Soviet Union. They weren't even a subject of the Soviet Union. They were an independent communist state like Bulgaria or Yugoslavia. It's interesting that it has a particle board bottom and the rest of it is solid wood. They don't build a single thing like that anymore. It would be a nice cabinet in which to build a tube set.

those knobs with the metal 'tube' bodges may be factory, as mine has the same, except knobs are chrome effect

@@Jayoldstuff1 oo, nice, any chance you could post the link?

Hi, my comment has just disappeared with some links in.
Is there a way to send you some links to schematics.

In the UK, 'radio' is commonly used as an abbreviation of 'radio transmission reception device'.
radio in uk is almost always meant to mean a radio receiver
@@andygozzo72 that device is not build to receive fm/am radio waves
@@mghz01 that radio featured IS ,its a normal 'domestic' AM/FM radio, i have one

no, leave it as is, they may be quite uncommon, maybe more so than the actual radios they were trying to 'copy'
