Sorry I did not intend to pick on any one in particular it was actualy directed to my own comment about the Panasonic FM series which has lower ESR.

No worries at all 😎

The new Panasonic FR series seems to have very good specs.
FC 4700/16v : 18 or 20 mOhms (16x31.5mm - 18x25mm) - LS : both 7.5mm
FR 4700/16v : 12 or 14 mOhms (12.5x35mm - 16x25mm) - LS : 5 / 7.5mm

FM 6800/6.3v : 14 mOhms (16x25mm) - LS : 7.5mm
FR 6800/6.3v : 12 or 17 mOhms (12.5x35mm - 16x20mm) - LS : 5 / 7.5mm

FM have a significantly lower impedance than FC. FR are as good as FM but have a higher endurance. Panasonic data sheet here.

However, I agree with RCruz etc. - there are more important capacitors, would be nice to learn a bit more about what the plans around RIAA are.

Hey Guy´s

I'm sorry to say that i close the GB when we have 200 Sets.

it is very much work for me to sort the components.



Now a small overview of the components:

All Resistors are Dale cmf55 with a tolerance of 1%

The capacitor for Riaa are Wima Fkp 2 with a tolerance of 2,5%

D44H11 and D45H11 are from STMicroelectronics

the rest of the semiconductor are from Fairchild Semiconductor.

The big electrolyte capacitors are Panasonic FR.

Mouser has not all components it in stock.I need to order a few components by Digikey.

I am afraid to say that the sets are now a little bit more expensive

The set now costs 85€.

best regards

Birger

Hi Birger,

first of all: thanks a lot for taking this burden, 200 sets are quite some parts to sort.:Olympic:

I am a little concerned about the FKP2, because I always match my RIAA caps for 0,5%.
2,5% is not close enough in my book. But maybe this was already mentioned somewhere before in this thread and there is a solution I overlooked.

cheers,

Juergen
