Cardas Caps Worthwhile?


Has anybody tried covering unused rca jacks on their preamp or a/v receiver with Cardas Caps? Another snake oil remedy or sonically worthwhile? Thanks, Ed

Thanks Dekay, I hadn't thought of cleaning tubes since I don't have any at the moment, but my friend just moved and his tubes for his VAV amp desperately need cleaning. How do you clean tours? Should I clean them the same way as the tips of an interconnect, or just a little alcohol rub? I have been using the little handy wipe type cleaner that XLO makes, and an air gun. It seems to do a good job. Haven't been to L.A. for a while now, but always have a good time when I do get there. I guess it comes down to price. I think most everyone would prefer the caps to other home grown methods if they were say...$6 a dozen.
I just use electrician's alcohol and cotton swabs if the pins are in good condition (also clean the globe with the alcohol). If the the pins are not in good shape I lightly use very fine emery cloth (think that's the name of it) and then follow up with the alcohol. Be very carefull if the pins are gold plated. I would like to try out the Kontak, but still have not purchased it. I just had my amp cleaned and spec'd, but will need to get some brushes (or maybe pipe cleaners?) for the tube sockets as I change tubes quite often.
Cornfed have you read in your Accuphase manual where it tells you to NOT use contact cleaner on interior jack connections? They advise that cleaning solvents could deteriorate pc board resins at the connection point. This being the case, it's certainly nice that those plastic dust caps are at least included. While I can see their point regarding RCA center-pins bonded directly to board traces, this doesn't seem to be such an issue with XLR in's & out's. I Kontact only my cable's connectors, XLR pins & RCA ground sleeves (on the pre, when connecting to RCA inputs) & the IEC power prongs. I haven't read any such cautions regarding possible deterioration of board-resins within any other manufacturer's gear, but certainly this could be an issue & takes the utilization of dust caps from 'tweak' to 'necessity' regardless of their material composition.
