Gary75 Posted April 12, 2018 Share Posted April 12, 2018 You guys ever ran a multimeter over your crossover capacitors? Noticed a bit of distortion in the V-21, I thought must be diaphragm related. Checked the values of both Leslie's they were so far out to the point of open circuit, One is a 70s other is a 60s Leslie. Noticeable difference on replacing all of the crossover capacitors.

OB Dave Posted April 12, 2018 Share Posted April 12, 2018 I dunno about distortion being caused by crossover capacitors, but when the capacitor value drifts, so does the crossover frequency. So the HF driver may be passing frequencies it wasn't originally intended to. I did replace the ancient caps on one of my Leslies and it did make a noticeable difference. I was advised to use metabolized polypropylene ones. The original crossover used weird cap values that are unobtanium so you have to put a couple caps in series to achieve the original 800 Hz crossover point.

WesG Posted April 12, 2018 Share Posted April 12, 2018 Old crossover caps let low frequencies in your V21. This can eventually crack the diaphragm if you play LOUD.

elif Posted April 12, 2018 Share Posted April 12, 2018 Old crossover cap's increase in value with age - how are these to be measured with a multimeter? Agree replacing can yield results like stock (inductors seem to be stable). Link to comment Share on other sites More sharing options...

I have a 122 right now with a raspy V-21, which is gonna die one of these days. In the mean time, it sounds fantastic. Moe --- Link to comment Share on other sites More sharing options...
