Need help ID'ing Elko Glatt caps in Canton speaker xover

[Too much stuff]

I have a pair of Canton GL210 bookshelf speakers that could use new caps in the crossover. I looked all over the internet but could not find a value for the following Elko Glatt caps:

2801
3690

Any help would be appreciated.

Thanks,

Tom

Ehm ...measuring them ?
Capacitor measurement till 50 uF is common in most 'testers' (DVM)

My DVM's don't have that function (nor do my VTVM's LOL), but I have a rebuilt Sprague TO-4 Tel-Ohmike which is remarkably accurate, but don't trust measuring an old cap and getting the correct value for what the cap was 20 years ago.

Please advise if there are any DVM's that can measure cap leakage at full rated voltages (well, up to 600vdc for the TO-4); then I'll think about upgrading to a newer DVM. Until then the DVM is for household electrical work and the HP 410B is for electronics.

Maybe someone has an electronic Elko Glatt cap catalogue they can pass along which I can browse through?

The online form at the factory doesn't work and the Cdn distributor hasn't responded yet to my query.

If you don't have a tester, you could make a simple 555 oscillator circuit and time LED flashes, comparing with known reference capacitors.

Thanks, but judging by the sound of the speakers the caps have aged and the values have drifted. That's why I need to know what the original values were.

or maybe ask Canton for xover schmaics.

I have the same problem with a similar pair, did you find an answer to your search?

They sent me a crossover schematic for a pair of 30 year old CT-1000's I have at home. It took a couple different emails but I eventually reached someone who was able to locate it.

thank you very much for your quick answer, I hope I get that information like you did... 'll let you know...
