Hi All
Clearing out my tool box and have decided to sell on the following to whoever wants them,
1) 2 DIY Audio "Ten Years After" Special reissue Mezmerize DCB1 boards
These will build a DCB1 which has relay input selectors, plenty of info in these amps out there and they produce a great sound ;).
These are mint - still sealed and unused to use Vinyl parlance :)
Description from the DIY Audio site
https://diyaudiostore.com/collections/pre-amplifier/products/mezmerize-b1-buffer
The Mezmerize is a direct coupled preamp (no coupling caps) based on Nelson Pass's B1 Buffer. It boasts symmetrical Salas shunt voltage regulators that use LED strings for very accurate voltage reference. Included in the board are provisions for up to 6 relays for input signal switching and an output relay for delayed start-up muting. Being based on the B1 Buffer, Voltage Gain should be close to 1.
"Ten Years After" Special reissue
The new PCB bring some improvements over the original:
The mounting distances are now compatible with the Hifi2000 perforated chassis baseplates that the diyAudio store carries
The five LEDS +/- voltage reference chains in the PSUs now work with equal current bias as in the vintage Hypnotize hot-rod version
*Note*
To Build these you will need a matched quad of LSK170 ±0.1mAs - Matched Quad (Grade B)
These are currently available from DIY Audio but they have limited stocks, they are not too expensive but hard to get once gone as the original Toshibas are no longer made. See link

Also - they are optimised for hot rodding to 200 MA as I understand it but this will sound pretty good! If you want more then you'll need different boards.

These are quality boards , not Chinese copies that you get on eBay etc.
Given import costs of VAT, Duty and postage I will sell these for £30 inc UK postage. I'm still losing out on the original purchase.
Paypal gift or you can pick up in Catford SE London, I also work in Croydon or Canary Wharf if this is easier for you and will knock off £3 for the postage saved :).
2) I have 1 spare Salas Mesmorize Type Input Selector Module
This is basically the relay selection module of the Mezmerize boards without the DCB1 bit. You can use this as a selector for any pre amp or build as a stand alone passive if you wish.

Again this is a quality board, unused and has a spot for an Alps pot or you can wire up something better if you want.
Will sell for £20 inc UK postage, again will knock off £3 if you collect. :)
pics to follow!
Forgot to add they both allow for up to 6 inputs .
Cheers Andy :)
