I have a Parasound P/HP-850 Peramp,i want to know if i can replace the AD712JN opamps (4Nos) with Burr brown OPA2134.
Thare are also 2 other opamps NJM4556A and NJM072,can i replace these with better quality Opamps. |

Thank you for responding, i will change them.
Even without any mods i think the P/HP-850 is the most value in preamps today. I use it for all my refrence when i build power amps, I am now working on a High voltage 115-0-115 power amp based on a leech.Output devices are MJL4281A and MJL4302A. I also have MJL21195 and MJL21196. Which of the above transistors are recommended for high voltage use? Thanks. |
