Connecting a 90s turntable to a 1958 stereo console

Post by Airwavesantiques »

I am trying to upgrade my vintage stereo with a modern turntable. Will I need to impedance match the table to the tube amp of the stereo? If I need a preamp , can I get one that is made for tube amps?

It's entirely dependent on whether the new turntable is fitted with a ceramic or a magnetic pickup.

If it has a ceramic pickup, it will probably work satisfactorily with no changes needed. Plug and play (assuming that your 90s pickup is still good, which it may or may not be).

If it has a magnetic pickup, you can either retrofit it with a ceramic cart, or purchase an inexpensive solid-state stereo preamp to boost the magnetic cart output signal voltage up to a level that the tube amp can usefully process.

Here's one solution: https://www.ebay.com/itm/263779173315?e ... R-q91sGAYw" -="window.open(this.href);return false;

Impedance matching here is basically pointless since you have a fairly low-impedance signal source (the pickup) feeding a fairly high-impedance input. So, the loading effect will be minimal.

Thanks for the quick reply. I will order a preamp. The cartridge is still good but magnetic. Thanks again.

Yep, you need a preamp for your cartridge for two reasons:
1. A ceramic cartridge has a relatively high, flat output, on the order of a volt or so.
2. A magnetic cartridge produces an output of millivolts. It also requires something called RIAA equalization.
