Is there a reason why you do not just solder the new capacitors to the same points as the original ones were removed from, albeit on the back of the PCB?

Regards,

you sure can, if they fit. the idea with soldering to the tube output and the output wire is to remove some of the pcb in the path.

Thanks for the information.

I have now replaced all six op amps as suggested, with noticeable improvement.

I now have capacitors to change but I am more used to electrolytic capacitors which are polarity conscious, are these capacitors not?
I just wanted to confirm before doing something catastrophic.

Regards,

Hi guys,
Based on the Audio Circle post I am about to attemp these mods, I shold be picking up my brand new black JD9 from the local Needle Dr tomorrow!!!
Jolida JD9 Upgrades

Obbligato 1.5 caps
Vishay bypass caps on above
Tubes (Ei vintage, Tele smooth plate, or Mullard long plate- one of these should be the cat's meow with the new cart)
B-Quiet with carbon/copper strands glued on top (damping)
Quiet Kote on top (damping)
Parts Express on bottom (damping)
Gold Alloy wire to replace key wires
Neotech wire to replace long run to circut board
Op-Amps
Power cable (very tasty Western Electric that is burning in at this moment)

Why all this hassle? My PS Audio does not have enough gain for the Denon 103r that I just put in a rosewood body!

Thanks for the pictures earlier in the thread showing where to solder the caps on the bottom of the board. I joined this board because I would like to mod my Jolida as well.

Question for you guys running the ClarityCap MR's, do you need to attach them in the fashion that the guy did from the other thread? I'm not really sure what the "sticky plate" things are, and there appears to be a zip tie connecting the two. Mine are on there way, I've had a stock unit that I've just rolled some tubes in for the last few months. Looking forward to getting some upgrade, my modded 302b is pretty special!

Thanks.

LoL - now that is one bright LED. :-0

Can you show a picture of the LED on the inside and the wires to it? Its quite easy to insert a series resistor to dim is down.

For starters try a 2.2k, if thats still too bright, go to a 10k.
