Luxman Power Amp Ver. 1.0 M-4000
Looking for a schematic and adjustments for Tim DeParavicini (EAR)
designed Power amp. This early model is distinguished by having an LF356 op amp as the input from the Alps vol. control. (There is no board at the Alps on this earlier version.) The later version was a DuoBeta version with the same model number, but while the concepts of the safety relays etc. appears to be about the same, the circuit boards are radically different. I already have the DuoBeta service manual. |

I already have the DuoBeta service manual. Try this guy: He just supplied me with a complete service manual for a Yamaha CR1000 receiver. Perfect reproduction and circuits also on CD. All for USD25 delivered to my home in the UK. Depending on where you are and how big the manual is, your costs could be lower. Recommended.! S. -- http://audiopages.googlepages.com |
