Telefunkin Opus 7

I put this radio on the Dim Bulb Tester (DBT).  It played, but poorly even with full line voltage.  For me the DBT allows a quick check of the IF transformers, Oscillator coils power transformer, AF transformers and more. It saves a lot of ohm meter checks.  

Restored this radio has a grand sound.  Much better than when received!  Most of the capacitors were split or oozing fluid.

IMG_2920.JPG (340221 bytes)The left cap has black goo oozing out.    IMG_2922.JPG (310458 bytes)The right has crystallized white fluid residue.  IMG_2919.JPG (162209 bytes)Most if not all of these black plastic like caps are cracked.
