I tried the above dc-blocker, but with 6,800uF/25V (small physical size) instead of the planned 10,000uF/50V. I arranged them for both F1 and BOSOZ.

When I turned on F1 and connected to J-Low (no others), about 90% of the buzz has gone from the transformer of F1 and the speakers. I could hear the very weak buzz when I brought my ear 50mm close to them. And, I connected all system and heard that the sound was cleaner, particularly with voices.

I had some experience of explosion of electrolytic capacitors. In general, I am very much afraid of using them whenever the use is related with over-voltage and reverse-voltage application. Nevertheless, they have been working well for continuous 6 hours. They were not getting hot. This means I might be no need to worry about another potential explosion hazard.

O . . . sorry for having interrupted the thread . . .

By the way, I expect that they will work also for Forte 1a.

Hi Choky

It seems that your circuit on the post #9 must have cap of big enough voltage rating. Otherwise, might BUMB !!!

Hi Choky

Thanks for the circuit.
By the way, I will create a new thread regarding the dc-blocker.

I speculate that the Audiovox were put in after-market.
