Finished up the offboard wiring last night and finally, after much fiddling cursing and dropping of screws, nuts and spacers managed to fire it up for the first time. Was in a bit of hurry as time was getting on so only managed to put it through my small 5w elac speaker but sounded pretty good (the speaker is in my 5w ax84 P1 amp, another thumbs up from a tube afficianado!). I hope to get it hooked up to a pair of 10 inchers in a 70w cab asap.
I'm using a scrounged PSU from a defunct laptop that gives 20v at 3.5A (Dell) so set it up using the 1.5K resistor on the regulator and got 16.69v on my meter. Two niggles when building, the ic socket had got it's legs mangled in the post, pity it wasn't stuck into the other side of the foam the tlo72 was in, and one of the screw and nuts wouldn't go together I figured a damaged thread: replaced both the socket and the screw/nut and had no further problems: except how small and fiddly it is to solder up ( hey I'm over 40 and my eyesight isn't what it was!
Plan now is to build a stompbox type preamp to run off the regulated 16.69v and put in the same case, any recommendations for one which will clean right up, but still get to a decent classic rock sound?
Oh yes, you can also chalk me up as one who'll have to file down the lip on the case lid to make sure it doesn't contact the ic tabs, doh!
