Description
This is a mono phono preamp and stereo cd buffer built by Susumu Sakuma himself. This is unique chance to own an original work of his!
You can find the schematic on the site with his works : https://www5.big.or.jp/~dh/work/02B_2.html
The original had an 845 as output stage, but through the years it was apparently changed to a 211. I also have a 'period correct' TDO resistor, to switch back to an 845, should that be required.
Phono input is the classic TKS27 MC SUT, going into a 5691 (red base spare included), followed by the Sakuma EQ correction circuit. Special in this preamp is, it has a prototype built by Tamura, that is the predecessor of the Tamura VL-SS, which is a choke with 3 taps, that allows the user to tailor the sound a bit. This prototype differs from the final production model, in that Tamura also installed the required resistors and capacitors (vitamin Q in this case) in the casing.
There is also a CD buffer input, consisting of a stereo input, that gets summed to mono by a transformer. Switch selects between phono or cd input.
Output stage is a 211 tube. A chinese 211 is included, as well as an Elrog 242 tube, for those who which to go all the way
Output tube goes through a Tamura F-2007 output transformer at 8ohms, connected to a volume pot, and back through a step-up transformer. Classic Sakuma volume control. That output transformer has each of it's windings connected to an output, for easy connection to a stereo setup
Rectifier tube is a Western Electric 422A tube, in excellent condition
Power transformer is rated for 100V, autoformer for 230V included if necessary.
Will include a Karmadon Gray replica arm, and Denon DL102 cartridge in the sale, as this is what the preamp was used on and built for
If more information is required, just send me a message!
This is a unique amplifier, in that none of Sakuma-san's amplifiers were ever commercially available.
Preamp is located in Belgium, but will ship worldwide.
