I looked at the link and did not see anywhere that they change the play EQ in the WM-D6C but they did talk about the IEC EQ on a Nakamichi deck. Does the part where he talks about the recording opam means that it is possible to use the very same opamp (NE5532) for the input section of the deck too? He says that it really is a plug'n'play mod, no need to change anything else. If you do a lot of recording with the WM-D6C it could make sense to replace the IC302 (the recording amplifier) too, however I didn't try that yet.' I replace IC301 (NJM4558M) with NE5532 in SOIC8. wrote this on Tapeheads: 'after an opamp replacement (the pro walkman) it is noticeably improved. I'm actually a pro recordist and if there's any unnecessary coloration and equalization I'd be happy to get rid of it. Still I wonder what Liberman have been doing this mod for during 20 years. I tend to totally trust him as he seems to me like a very thorough technician. There is little reason to modify these as it then makes them harder to repair.' Sam Palermo, when asked to do this mod very kindly replied me that 'The Play EQ is either 70 or 120 uS and I would not fool with that. What are these resistors doing exactly? Is there an overall equalisation curve to the device?

Could anybody please help me understand that? I knew that it's possible to optimise the deck for a specific cassette by soldering-unsoldering some bias pins and I had guessed this only interests the recording circuits. 'Custom adjust playback eq resistors for flat response'. used to make a few mods-optimizations for pro recordists, one of them remains quite unclear to me, here First question: Liberman sound in the U.S. I own 2 of these and use them since one year for field recording, I like them so much that I'd really like to better understand a couple things in order to improve them even further.
