DB systems apparently still makes the kit that they offered in the 80s, I just sold my old one. It was mentioned in Stereophile in the last year or so. I think it is $69.95, not a bad price considering it was $39.95 then. DB is a good company but one of the stealth variety, I had no idea that they were still going.
MM cartridges and capacitance
Can someone explain to me why an MM cartridge would "want" to see more than the minimum possible level of capacitance loading?
This question is provoked by a lot of commentary on "that" "MMs are great" thread, and a question someone just asked, and the fact that I have two phono stages (granted, older Japanese stages) which have multiple capacitance settings and I have never gotten a "better" result from being at the high end rather than the low end. In many cases, it doesn't seem to make a difference, but so far I have not gotten an improvement from raising the capacitance setting.

Thanks, Stan. I just checked and sure enough my "Phono Equalization Kit" was made by DB Systems. It provides polystyrene capacitors, mounted on rca plugs, with values of 100, 150, 200, 300, and 400 pf; 100 ohm 1% metal film resistors mounted on rca plugs for use with MC's; a pair of spare plugs; and a pair of y-adapters. The part number of the kit was DBP-6. The instructions also made reference to a DBP-11 "Capacitance Loading Switchbox," which could accept inputs from two turntables, provide independently selectable capacitive loading of each cartridge, and allow the user to select which cartridge's outputs are routed to the phono stage.

Here's their website. Looks like those products and many others are still available: http://www.dbsystemsaudio.com/ Best regards, -- Al |
