Pionier ZPR - Czecoslovakia 1955

I've recently purchased an old radio in Poland, manufactured by Z.P.R. PIONIER
in Czecoslowakia in 1955 (mod. Pionier-Czecoslovakia 1955). The photo is below.

I am currently restoring it and I am looking for information about the
history of this company (that I think was a subsidiary of Philips) and
if possible, technical information about this model. Could you maybe
help me to find out where can I find this information?

I found some information by googling "Pioner U2". U2 is afaik the type name of the set. I repaired one some years ago for a friend of mine. Attached to this answer you find some alignment information which I wrote down, when I was repairing the radio. Perhaps it's a bit helpful for you, even it's in german.

Presented radio "Pionier" has been produced in Poland in Z.P.R. - Zaklady Przemyslu Radiowego (it means - Factory of Radio Industry) - later "Diora", in Dzierzoniow (Silesia). Not in Czechoslovakia. There were different models of above radio in different housings - wooden or bakelite. I have six different in my collection.The model in the same housing with power transformer was called "Mazur".

Hello,

    I am an American living in France and have restored many Philco, Zenieth and other American radios. 

  I also restore and scratch build Fender Bassman and Fender deluxe reverb amplifiers, The thing is, I always have the service manual with all the resistor values and capacitor values. Im currently working on the pionier U2, but the layout is blurry and the schematic doesnt show placement of the componants .

   Is it possible that you have the complete service manual ? With clearer photos ? I watched 6 you tube videos of a guy building one from a bare chassis, he had a service manual with at least 40+ pages,  I dont speak Polish so it was difficult to follow his work, I speak Russian, German, Italian and French. Is it possible you have this full service manual and I could buy it from you ?

Please let me know,

best regards,

John Landi

Hello John,

maybe the wiring diagram for model pionier U2 [wood "old"] - Unitra will help.
