This was serviced July 2018 by a PinkFish member for me. He followed DADA instructions for refreshing the 34, but used better quality parts. https://www.dadaelectronics.eu/uploa...anual-V3.5.pdf
The TL072 have been replace with sockets which currently house LME49720NA and the TL071 with sockets and LME49710NA . So you keep can as is or try opamps of your choice.
Case is in very good condition, some slight marks on knobs. Balance working perfectly.
I will also include 2x5 pin DIN -> RCA cables for input and 4 pin DIN -> RCA for output. Also comes with original manual.
