bombay works only for the money and not the lulz. Not the best way to do it - but access to workshops and quality tools is actually impossible here. quick spray of varnish, and we have a bow-teek knob ready to go. then dry sanding frrom 200 through 600, wet up to 2000. I then used a rough abrasive disc to get the round shape, smoothed and contoured using the chisels, put in the three grooves as well. drill into vise, and voila, we have a DIY lathe. this was done using an industrial grinder (just gets worse, eh?).ĭrilling a hole into it and securing it with a thick screw, i then had the screw cut in half so that i could affix the shaft into the electric drill's chuck. I found a square piece of solid wood somewhere in the factory (that's where i got the old burma teak for the sides too), and got it roughed up into a somewhat octagonal round shape. and some bargain bin wood chisels that i picked up in a home depot in germany during my student days there. finding the alps pot that i used was a stroke of luck in itself, normally the pots here are REALLY bad.įed up with the market offerings, i took it to myself to turn a knob. The only knobs you get here are effed up crap-looking plastic fan regulators. i'm very disappointed with the cosmetics on the whole, and plan to redo them sometime.Īm quite sold on the CCS design now though, and wonder what it'l sound like when used in guitar amps.i plan to use a 2N3055 for a customer's guitar amp that i'm building right now.
#Lathe pulltube Patch
the big white patch on the frontplate is a photo of my dad that i had laser etched.
It's not the best pic, and it's a bit gunky too (never again am i doing chrome plated Al!), but it'll give you a fair idea of what it looks like. and they smell pretty funny too, not surprising, since they've spent the better part of 35+ years in an attic. the speakers are some ancient sonodyne (indian make) TLs i found in the attic, they sound ok, but have terrible bass response. a switch and LED have to be put onto the front. should i reconnect the speaker ground or leave it floating? ohm's law tells me that 900mV/40mA = 22.5 ohms, which is roughly the size of the resistor setting the voltage on the LM317.Ģ. the sound was fine, and everything was ok. i panicked at first and checked the tubes for any signs of redplating - nothing at all. when i set the bias for the EL84s, my DMM read 900mV on each tube. Just a couple of things that thoroughly confuse me:ġ. Removed the switch entirely, and the oscillations just disappeared
