61+ caps @ $2 ea. vs $0.12 each for the 'lytics just seems like a lot to invest, compared to the street value of the instrument.. (at least here in the NY area).
I'm not always a cheapskate though :-)
I've recapped two Omni 2's in the past few years - on the first (which was in really fine shape) I sourced some NOS tants - lovely red globules.
The next time around I went with cheap electrolytics since the unit was rather beat up - the result was nowhere near as aesthetically pleasing.
I now have an Arp Quadra on my to-do list and I will go with tants on the voice boards and Sprague in the supply because of the condition and rarity of the instrument.
I agree that adding a second board to hold the larger cased caps wouldn't be worth the effort..

This weekend's project:: Octave Kitten rev 1 - beautiful shape, w/ a half-dead power supply and who knows what else....

get the tantalum if they wanted an electrolitic they would of put 1 there and tantalum caps are not that expensive----- Original Message -----From: babouche369Sent: Tuesday, November 15, 2011 6:17 PMSubject: [vintagesynthrepair] Re: Arp Omni 1 master oscillator / buffer question.I know; I tried to do so on the 22uF. My local dealer only had radial for this value, but once back home, I was disappointed; the footprint is far bigger and there not enough room on the PCB. I bought an extra PCB to set the electrolytics, but the complexity doesn't worth the saving.
I have to check with another dealer the other side of the town if they have axial.

china is the best place for tants and singapoore
which is where i get mine from and they come in red blue and beige
i have had batches of 30 for £0.20
each
i also use a local british whole saler who
buys in bulk and sells them at resonable rates unlike rs and digikey and others
as he only has himself for over heads unlike these multi billion
companies
