Dynavector P-75 mods?


Hi, I've recently acquired a P-75MKII, and I'm thinking of having it modded. Anyone had one done? Most of my gear has been done already by Dave Schulte, with great results. Just wondering how much can be gained by modding on something this good already.

Thanks all. Dan

The battery idea sounds like a good one, you'll have to re-post after you try it. The RCA upgrade sounds good, too.
I'll have to try that.
Thanks much, enjoy,

Hi,
I recently bought a P-75; made necessary when I bought an Aesthetix Calypso to replace my Krell KRC-HR which had a KPE phono stage fitted. I have been setting the P-75 up and learnt that:-
1) A 12v battery supply is a lot better than the mains wall-wart. Background hash is reduced and clarity improved as is soundstage and ambience performance. This was with ten 1.2v Nicad AAA batteries wired in series. I plan to get a 12v sealed lead acid battery which can be easier to maintain by trickle charging when not in use;
2) Also, it looks like that the phono enhancer mode does not work for all cartridges, at least not for my Lydian Lyra which has a low impedance coil - 2 ohms. With the P-75 set to phono enhancer, loud (alarmingly loud) cracking noise would come through the speakers whenever there is any highly modulated signal on the record being played. I think the problem is due to the very low coil resistance of my Lydian cartridge. Certainly, the cracking noise got worst when I set the Phono enhancer mode's impedance to that for a high impedance cartridge. But even when set for a low impedance cartridge, the cracking noise is still there. So I seem to have no alternative but to run my P-75 in the MC high gain setting.
Trust this helps.
I replaced the stock power supply caps with nichon muse, they are about twice the size of the originals,but well worth it when I powered it up. It's as though a "veil" had been lifted from the soundstage. IMHO, a worthy upgrade,considering the small cost.
