Default Tandberg 3041x Capacitor Replacement.

Hello

I'm currently going through recapping and testing the electronics in my Tandberg 3041x reel-to-reel. So far, I've sourced all but one capacitor replacement.

The value in question is 500uf 12v; there are two, and they are for the left and right audio amplification.

All I've been able to find available is 470uf 16v. Anyone with more experience with Tandbergs knows if I can get away with it.

I've attached a snapshot from where it sits, on the circuit.

Thanks

Electrolytics generally have a wide tolerance especially older parts.

The standard replacement is 470uF for the 500uF part and you will find this will work fine.

The slightly higher voltage won't be a problem either modern parts are much smaller and unless you go for a much higher rating say replacing a 10V part with a 100V part it will not be detrimental to the life of the capacitor.

So the part you have identified is a good substitution.

Cheers

The voltage rating is the theoretical maximum for the electrolyte within the capacitor before electrostatic breakdown due to high E field strength. Choosing a higher rated capacitor is no problem, and is something I often do.

The 470uF replacement will be fine too, it will be used for biasing, and at audio frequencies the 470uF/500uF will be bypassed as intended.

By 'recapping', are you replacing all the capacitors? Or have you identified a few as defective?

Hello, there were a few that had become loose on the board so I thought I'd replace them, it seems someone has been in before and done some questionable soldering work.
