This is one of the common variants found on the portastudios and includes the pcb

If you see the photos you will see its actually much better than others advertised at much higher price

I have various off cuts here for the 800 series about a meter long and the 400 series a bit shorter

Fostex G16S G24S input channel 8251878-001 r/p amp two variants Style:Fostex G24S C37=0.22uf this is number TEAC 52100748-02Some 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
