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.


The left cap has black goo oozing out.	The right has crystallized white fluid residue.	Most if not all of these black plastic like caps are cracked.
The electrostatic tweeters need work.		Deteriorated foam rubber.
	There is hard ribbing to support the rear diaphragm.	Clean the contact with a cotton swab and contact cleaner.	I can hear the buzzing of the capacitor checker in the tweeter.	Sounds nice with the FM radio playing some smooth jazz.
