Amp Tech Simulator @amptechsim
Fatal voltage. No funeral. Build, probe and repair real tube amps and pedals, one part at a time. Every circuit is live, and so are the filter caps. Coming soon amptechsim.com Joined September 2026-

In the game, the pilot comes up dim with the bulb limiter in line, and full with the bulb bypassed. The lamp follows the heater voltage from the circuit solver. amptechsim.com
A 12AX7, one turn. Two triodes share the bottle, with a mica at each end. The getter ring sits above the top mica, under the silver it left on the dome. A 3D render from Amp Tech Simulator. amptechsim.com #12AX7 #tubeamp #gamedev
A 6V6GT, taken apart along its axis: glass, getter, micas, plate, beam plates, grids, cathode, heater, stem and base. A 3D render from Amp Tech Simulator, a PC game about building and repairing tube amps. amptechsim.com #6V6GT #tubeamp #indiedev
Amp Tech Simulator: the output valve. Glass, mica, the grey plate box, the getter's silver flash on the crown. The corner panel is the base: seven pins in an octal ring, one seat left empty. amptechsim.com #gamedev #indiedev #tubeamp
Every number on the Amp Tech Simulator bench comes out of the solver. None of it is scripted. Amber when the solver had to work for it. Red when it worked far too hard, or could not solve at all. Our hardest note reads amber. amptechsim.com #gamedev #indiedev #tubeamp
Amp Tech Simulator: a good joint, and a cold one. The top one flowed. Solder wet the post and the wire and pulled into a bright fillet. The one below never flowed. It sits grey and lumpy, the strands showing through. amptechsim.com #gamedev #indiedev #tubeamp
Read the bands. Brown black green gold is 1 megohm, half watt carbon composition. The cap reads 2J223K: 0.022 uF at 630 V, plain then banded at the outer foil end. 3D renders from Amp Tech Simulator. amptechsim.com #gamedev #indiedev #tubeamp
Amp Tech Simulator: the first build, laid out the way a single ended amp sits. Two transformers at the back, three bottles in a row, the jewel lit on the front. Every part on it was built from its drawing. amptechsim.com #gamedev #indiedev #tubeamp
Same can. One is 1 uF, the other is 25 uF. Read the print. Amp Tech Simulator, amptechsim.com #gamedev #indiedev #tubeamp
In Amp Tech Simulator: a good joint and a cold one. The good one flows smooth and hugs the lead. The cold one sits dull and lumpy on top. amptechsim.com #gamedev #indiedev #guitaramp
In Amp Tech Simulator: a CAT III probe with 4 mm of exposed tip, and a CAT II with 19. Two tips. Two ratings. amptechsim.com #gamedev #indiedev #tubeamp
Rebuilt this alligator clip from the maker's drawing: meshing teeth, a pivot rivet, and a formed steel channel. Amp Tech Simulator builds its parts from published dimensions. amptechsim.com
