Great work, man. Totally concur with you on the E80CC tube. I'll take it over virtually any 12AU7 in the 'proper' Crack + SB. By 'proper' I mean a BH Crack who's resistors are setup to handle the E80CC's tube optimally.

Did you look into the small board w/ a switch that some gents over on the BH forum fashioned? It allows you to run three different types of tubes with resistors/values (and whatever else) that are optimized for each 12v tube type that the BH Crack can handle (i.e. 12AU7, 12BH7, E80CC). I really encourage this as I've heard a BH Crack + E80CC with the switchboard it sounded phenomenal.

I agree, perspective is always good. For me, the desire to accumulate fancy stuff is just as alive and well in DIY as it is in buying manufactured equipment. It just takes more time & effort and involves more swearing at the soldering iron. Crack + Speedball sounds great and there's not necessarily any compelling reasons to go beyond that unless there's a desire to squeeze out the last drops of performance from the Crack, and/or have fun and learn about the changes that component upgrades can have in a simple circuit. You make the good point that not every mod will bring about a positive change for everyones tastes. Plus, although there is usually great help available on the BH forum, the modder has to accept that they are heading out into the wilderness somewhat. - I am digging the E80CC.

Somehow most of the 12AU7s seem a bit rough around the edges now - in comparison. Even the Mullard CV4003 which I always considered to be smooth as hell. How does one go about getting a switchboard? I guess you have to submit a PCB design and have it made. I've never done this before.

Would anyone have a design or could offer some help with this? If not, I might just optimise it permanently to E80CC parameters. Some people like the E80CC and others not so much. I like the Telefunken 12AU7 and it would lean towards the more even & neutral end of things - as much as that can be said about the Crack. If that is the direction you're looking to steer things then the E80CC would be worth checking out.

Crash Bandicoot 1 Iso. I don't really have a huge problem with the stock tubes but the Speedball/Mods exposed some minor frailties in the 12AU7s as a whole. The E80CC sounds more controlled & less grainy to me. But I would advise to maybe avoid it if you prefer something warmer and softer. Otherwise, it should be a fairly cheap experiment to try, if you can pick up an E80CC for around £20 on eBay before deciding if you want to make any permanent changes or implement some kind of switchable resistance solution.
