Some of the Disco music from the 70's is mastered without any compression, at least all of the minor collection I have lacks compression.


The initial part of a really tight kick drum is very dynamic/peaky, one can imagine that a constantly peaky kick over a period of time will cause the capacitor to charge/discharge with more power and frequence of occurence than for example a classical piece, or some more modern masterings with more use of compression, which would cause you to lower the volume and therefore also peak power. I may be wrong, but that is how I look at it.

I just get this picture of a 90 year old with a troubled back trying to Disco like he was 17 in my head when I look at that pic in the first post.

The caps over 30years old.....Now what we have with Acoustat are some of the BEST sounding panels EVER made!.....But most think thay well just play for ever....goodluck with that an any 30+old speakers...it more like the bias ..that should be at 5k...is in your 2+2s like most other Acoustat are runing at 3500 after 30years of cooking in the box...that means the cap that pop,et...looks to your amp looks like a DEAD short...ESL speakers like all just play sounds...disco or what ever..
Get the bias up...Re-bild the bias boards.....like $50.Us.... you get 3db or more output of the 2+2s...An if you dont get the bias back UP to the 5k.. you can KILL your tranfourmers....then you can spend big $$$$....Spend $10.Us.. an get two more caps..an you back at the Disco...
An it looks like there is some dog hair in the box that can get damp an short pull down the highV...Your lucky if all that POP,et is the cap!
goodluck

Serious response:

Do not put an electrolytic back in there. Change it for a stack of polypropylene caps that equal the same value approximately. Does not need to be exact. There is huge overlap between the HF and LF transformer's operating range...

...the effect on the mids will be gratifying and good. You will wonder why you didn't do this sooner.

The new caps do not need to be exotic at all. Just rate the voltage above 100vdc, higher is better... they can even be <gasp> motor starting caps (as long as they are polypropylene). Keep the film cap that is already there if you like.

They do not need to be all the same value, just add up to what yo need. You can tie them together for mechanical stability if needed. I made some pcb backer to hold them for a client once... much neater. If neatness counts.
