Re: NEOTEK: Series 1 recap

[Ike Zimbel]

Hi Paul,     Since no one else is tackling this: If you can fit the WIMA caps in other places where there are 10uf non-polar caps, you will not regret it. For the de-coupling caps (probably 2.2uf/50v, these are the polarized caps near each chip), any larger cap is an upgrade. 10uf is stock in the later boards. I have used 22uf, 33uf and 47uf all to good effect. Use good quality caps here...usually a 105 degree temperature rating is at least some indication of lower ESR (which is a good thing). Good luck, Ike SAR wrote: This is for all out there in Neotek land—   I have a Series 1, and I have replaced some of the chips with BurrBrown 627’s at the bottom of each channel, and in the master section. I kept the TL074’s in the pre and EQ section of each channel. It made a stunningly wide sound stage. I was impressed. I am now recapping, and have done the master, power supply, and 1 channel, but I am using the original Nichicon’s; and original values—with one exception:   I am using WIMA 10uF MKS polypropolene series (they are brand new small designs) for the non-polars near the BB 627’s.    What I need to know is what caps to bypass, and what values to upgrade; and in what places.   Can anyone give me any suggestions?   It is an 16X8 motherboard ’84 Series1, with 6 older 1E ribboned channels modified to molex.   Thanks for any help-----   Paul Sinclair   -- Ike Zimbel Zimbel Audio Productions Ltd.
