Capacitors for Linn Linto phono stage Recap

imhififan,

I made a final list with purchase links and (99%) matching dimensions. Please approve it :-)

1) 4 X Rubycon 105c 200v 220uF 9030aw:
The original caps are MXR series which are no longer available and had a lead gap of 10mm
https://pdf1.alldatasheet.com/datasheet-pdf/view/145362/RUBYCON/MXR.html
This one is actually much better rated and has a narrower leads gap of 7.5mm (non issue in my opinion)

12000 hrs at 105c
Leads gap in spec : 7.5mm

2) 20 X Longlife RSH 105c 35v 100uF 9940
https://www.digikey.co.il/en/products/detail/nichicon/UPX1V101MPD1TD/4321159

As for Tantalum SMD caps, they only come in box shape and I wasn’t able to find them in the cylinder shape I need.

You did a great job for the capacitors selection! 👍👍

Some suggestions:

IMO, if you want those radial capacitors sat nicely on the PCB, lead spacing is important, and its diameter as well. Newer capacitors for the same rating tend to be smaller, you can choose higher voltage rating capacitors to match the existing space.

For surface mount capacitors, "land space" is very important! Please measure the existing space to ensure the replacements can sat and soldered properly.

If size is permitted, you may also consider Nichicon PCX series for its excellent ESR and Ripple Current rating.

IMHO, YMMV. 🤞

"IMO, if you want those radial capacitors sat nicely on the PCB, lead spacing is important, and its diameter as well. Newer capacitors for the same rating tend to be smaller, you can choose higher voltage rating capacitors to match the existing space."
I tried to search higher voltages caps but all were too large or too tall. The Large caps in the brilliant PS are very tight and only the one I chose will fit in. I'll carefully improvise a horizontal twist in the leads so they fit in...

"For surface mount capacitors, "land space" is very important! Please measure the existing space to ensure the replacements can sat and soldered properly."
I compared height and diameter of the barrels of the 2 SMD types I want to purchase and they match the dimensions of the 2 SMD types I have in my Linto.

"If size is permitted, you may also consider Nichicon PCX series for its excellent ESR and Ripple Current rating."
Unfortunately these are way bigger than the ones on my Linto

I guess at this point, I should go ahead and order what I listed, right ?

YES! Go ahead, you did a great job for the capacitors selection! 👍👍

I had a great teacher ;-)
It will take the parts 2 weeks to arrive, I'll assemble them and report the result...
