Fostex G16S G24S input channel 8251878-001 r/p amp two variants

Some news here

I was informed by Costa AKA "vyper883" from Tapeheads that he found there are 2 versions of this card with the same pcb number but C37 etc has been changed probably because of differences in the head, so C37 can be 0.15uf/R150 for the G16S and 0.22uf/R220 for the G24S.

There maybe other part changes and in theory I am guessing they both work but not as good, You can mix the single and 3 chip boards as long as you get the correct C37/C80 variant it seems.

Ok so there is some story here

This is a panel from the G16S and also the G24S, commonly techs call this the "three chip one"

I am selling these boards in 2 forms, initially sold as seen and 90% chance they do not work

I had to list them as they would get lost.

The problem is that they used very early electrolytic SMT capacitors and they fail , you need to change all of them, often I bid on a unit on ebay say 150-200£ in good condition and loose to someone who buys it at 600£ that's really daft as you need to recap 16 boards and that's a lot of time, the 24 track version must take many  days of tech time plus the parts and retesting etc.

I am going to initially offer as is and you recap them, or in spring a tested recapped channel, I see some guys doing this service and its 1200£ and you need send in your own cards. 

That's a hefty chunk of money for most Music guys, So I will be selling like one to two channels at a time so people can fix their machine bit by bit.

Probably I will sell the Channel as is ( needs recapping) or a recapped channel tested and ok to go, or lastly you send me your channel and there is a recap charge per channel.

I have not really looked deeply into this yet as many people are quite competent with a small soldering iron bit. there are about 30 caps to change

I may offer like capacitor kits so you can just order in one hit as its tricky to order as some suppliers have some caps others another, last time I looked at this I needed to buy from 5 suppliers which is a headache as have all the taxes etc

This is the 001 version, there is a single chip version
