Description:

This radio has the same chassis and electronics inside as the as the Aristona SA2025A. The main difference is the wooden cabinet and the larger loudspeaker.

Repairs:

• Volume potentiometer of 0M4+1M6 is renewed.
• Coupling capacitor between EABC80 and EL84 is renewed.
• Screen resistors of the EBF80 and EF85 are renewed by 82K 2 Watts. The reception of the AM and FM broadcast stations is now much better.
• The remaining paper-tar capacitors on less critical places are replaced for a better performance.

Performance:

The radio is repaired regarding to the factory specifications. The sound lacks in the top high frequencies. The bass sounds very full and deep.
