The Eros tape preamp must have been my longest audio project by far. I started the build quite soon after receiving the kit, but every time I hit an obstacle, I'd set it aside for a day or two, and as I turned to other projects (audio and not-so-audio) those days would turn into months...eventually it became a multi-year journey. I posted earlier this year about the final problem, where I could only get ground hum out of my Technics tape deck. That was my fault, unsurprisingly, as the output cable + six-pin connector I soldered together for connecting to the wires from the headblock were reversed - signal to ground pins and ground pins to signal. Yes, I really am that crappy at deciphering a schematic.
So after resoldering that connector/cable...joy! Actual music. I think this deck and preamp are going to be very happy together.
Sadly, I don't see another Bottlehead kit in my near future. I went with a Japanese kit phono preamp for my turntables, and the other Bottleheads I once entertained hopes of purchasing (integrated or power amps) are climbing the cost ladder for my budget. A few years ago that might have worked, but the yen dollar exchange rate is painful right now, and it's unlikely to return to where it was. The only low-hanging fruit is the Speedball upgrade for the Crack.
Paul and Doc. B, thanks again for your patience and all the assistance.

Don't beat yourself too much about the headblock connections. A lot of those schematics were not particularly easily read when they were made, then after they are scanned and made into a PDF, things tend to get a bit worse.
I'm glad you got it all up and running!

Thanks Paul
I made peace with the fact that I'll never be an electronics adept. I'm grateful to learn anything, even if it's the slow way. At the time I bought the Crack kit and my first R2R tape deck - perhaps 15 years ago? - I knew nothing at all about electronics and had never used a soldering iron. Everything I have learned since started there. R2R is a very good medium for realizing you're going to have to open a component up and do some things yourself! Now I'm reasonably comfortable doing a certain amount of repair work on other vintage audio.
Many aspects of electronics/circuits will remain a mystery to me - it's a field in which I'm more comfortable following detailed instructions to the letter than puzzling things out - but the building is fun, and I'm happy to learn little by little. When there are blunders like the ground/signal miswiring with my Technics, I remember them for next time.
