Thread: NAD: Thunderstar Bass Amp

    Errrrr.... I guess I had my story wrong. Amp must have been her husband's. I just assumed it was her dad's since he passed away recently. Anyway, carry on and enjoy!

    My restoration of the cabinet is almost done and I think it looks freaking great. On to the amp chassis next which might be a bit of a challenge, but apart from its apparent desire to try and kill me, it seems to be pretty sound so that work will be largely cosmetic aside from neutering its homicidal tendencies.

    Bob will, indeed, be your uncle. So far the toughest nut to crack is the grill cloth. Itís not bad, but the cab looks so nice now it sticks out. Tonght Iím trying resolve and that will probably be my last attempt because itís one of the things thatís not easily replaced.

    Iím thinking of doing an entire article on the restoration.

    That grillecloth is unobtanium, that's for sure.

    One of my favorite bass amps I've ever played through! I really miss mine. I had the blue-face model as well. I like my current Thunderbass amp too, but the Thunderstar Bass amp was a little more my flavor and I wish I could articulate exactly why.

    Back when I didn't know better, I'd take the speaker out of a cab, put it in the shower, spray the grille cloth top to bottom with 409, wait a little bit, and start rinsing with hot water, and just watch the grunge wash out and down the drain.

    Dry the cab out quickly and viola, near restored grille cloth.

    No brushing of any kind, just spray and rinse.

    Before and after.

    I'm not real happy with the speaker grill, and I may have made it worse, so I'm not posting that until I know for sure. I'll write up a detailed article with everything I did, how, and why. Of course there will be lots of pics.

    For now, I've removed the death cap, added a temporary 3-prong plug (I have a longer one on the way with proper strain reliefs), removed the aux AC outlet from the circuit, removed and de-rusted literally every piece of metal I could get to outside of the chassis including the nuts on the input jacks and the individual screws on the amp corners, cleaned the knobs, de-oxed the pots, scrubbed tolex until I can't feel my shoulder, glued loose bits, cleaned all the nasty dust off of the tubes, and added new weather-stripping between the chassis and the front panel.

    After a half-bottle of phosphoric acid goo over six applications did almost nothing to the chassis rust, I took a rotary metal brush to it. The chassis is a disaster. The rust was 1/8" thick in spots, but it's only on the top. Honestly, the only right way to solve that was to take everything out and sandblast the chassis, but I was unwilling to put in that much effort since this has burned a lot of time already and point-to-point wiring kind of freaks me out when thinking about a full disassembly. I gave up on the idea of trying to restore the chassis and settled for trying to stop any more rust.

    It's time for a post-amp-overhaul-cocktail.

    Do you remember what cabinet you had? Or did you just have the head?
