For Sale A One-Off Rebuilt Quad 34 Pre
Bought this Quad 34 Preamp off twotone aka Tony and he in turn got it from Quad expert Robert.
Rob did a special rebuild of the 34 while he owned it. The Pre has a:
- Fully rebuilt PSU
- CMOS 4066 ICs upgraded to socketed Maxim low impedance, low THD version.
- Line stages upgraded with OPA134/2134 devices.
- Film output caps.
- Upgraded coupling caps, some replaced with wire links where appropriate.
- Rebuilt phono stage with metal can LME49710HA devices (with PSU bypass caps). Very low noise.
- Improved low end extension on the phono stage.
- 1.5 output to suit most power amps
It comes with the optional MC card, plus an upgraded MM card set to work with most Ortofon, AT and Goldring cartridges.
Tony meanwhile modded the MC card, so it can take a Denon 103 MC.
All these updates make the Preamp about the highest spec 34 you'll find.
Conversing with Tony about this, he thinks the Quad 34 is worth £400 because it is a one-off. He said he regrets selling it and I know I probably will as well.
The 34 can be picked up from near the Chelsea & Westminster Hospital in London or I will send it at cost. Please PM me if you're interested.
Thanks,
Jack
