    No you mixed up TTU55 and TU56, it's only the TU56 that can hold G888 (haven't seen G882 in the drive). What I know about all TC's have the G88x cards in them. The G888's goes in the drive only when...

    Have mounted one of those new bulbs now, works like a charm! Not 100% stable on passing the maindec DHRKB-G every time though.

    I had to change many diodes and they broke down after a while. So the memory broke down over and over again.

    One interesting thing was that I only had to change diodes on one of the diode boards....

    Had a recap reading my restoration blog, seams like I never used the 2N3725. I intended to use them as replacements for the DEC1008's on the G221 boards. I found the 2N3444 transistor, it's a perfect...
