NEVE 1081 DIY

NEVE 1081 MAIN PCB AND AMPS  VERSION 8 download here!

UPDATES:

05.06.09
error on component placement BA312
The resistor “R52” (see schematic from AMS site) is NOT 6M8 but 15K. Its between the BA338 amp A5 and the BA338 amp A7. (now V8)

Thanks to ekadek for the info!

9.12.06
errors on main pcb marked
(2800pf, 220n,470n,150µ)

25.11.06
BA306 R5 is 1K2 (Thanks Jarek!) >> now version V7

22.05.2006 BA338 and preamp stage is working with the component values in V4

ERRATA:

BA338
22µ16V polarity wrong
10µ/25v polaroty wrong
10pf has to be 10nf mks
resistor values changed
*BA338 is working*

BA308:
10pf has to be 10nf mks

BA340:
10µ/25V polarity wrong
22µ/16v polarity wrong
100k resistors at the ouput of the bipolars is wrong - must be 1R5
4K7 has to be 47K
4K7 has to be 47K
3K6 has to be 36K
BC441s (output transistors must be cooled) you can use BD139 and BD140 (but check the pinout [its different] )


MAIN PCB:
R? = 1K5 at preamp section
6M8 resistors can be 4M7....
two styroflex capacitors has to be 2800pF instead of 2700pF
22nF has to be 220nF
47nF has to be 470nF
100µ/25V has to be 150µ/25V
