Main-In Service - Janus Preamp Recapped & Rechipped

This includes priority return shipping.

The Janus preamp is a stable and versatile design. However, all of these units are getting quite old - most particularly the electrolytic capacitors. We sell re-capping kits and highly recommend them as a first step if your preamp is starting to make some of the tell-tales sounds of cap failure. Or you simply want to have a little better definition in the highs and lows. But the real game changer with these preamps is upgrading the op-amps. In this service we do both. Here’s what it entails:

  1. You send us your Janus Preamp (please pack it well)

  2. We test it to see if there are any issues beyond regular service.

  3. We replace all the electrolytic capacitors w/ high quality modern or NOS capacitors

  4. We first install 8-pin DIP sockets

  5. Then we install some nice OPA2134’s (or similar quality) op-amps

  6. We test everything on the scope and through an amplifier.

  7. We mail it back to you with a little bag of your original parts.

We use professional soldering and desoldering stations. High grade Kester solder and we use some of the best parts available. The sonic differences are very worthwhile and we’ve tried to make this service somewhat cost-effective for people who don’t have the time or tools to do it properly.

Let us know if you have any questions. Please contact us prior to sending your unit. All units can be sent to our workshop location:
