i'd like to be able to confirm if the motor is alive or dead if anyone has any tips for that, or any other reccomendations. In any case, if anyone could point me in a good direction that would be great. I have found that using the GTR tempered tuning puts that old Gretsch shimmer to the highest plane. You can strobe ( pun intended) through the settings and find tempered tuning settings. i don't really know what it should look like or if it could be frying transistors. 112 Johnson City TN 1 I have an older Peterson Strobe tuner. on the scope the signal looks like a spike up and then down. The other thing i'm not sure about is the signal coming in from the tuning circuit. however bot coils are not open and have the same inductance so i'm not certain how to confirm that its dead. This has been a problem with our Node (Peterson) strobe tuner - so much noise We open it up and get to the wheels to get to the root of the problem. Like Peterson’s high-end units, the Stomp Classic is accurate within 0.1 cents, making it five to 10 times more accurate than other pedal tuners. What i'm considering now is either that the motor is dead. E-Mail: Accuracy: 0. The heart of the Stomp Classic is its large, half-circle backlit LED, which provides exceptionally accurate and easy-to-use spinning wheel tuning feedback, even in darkness or direct sunlight. with the motor board removed everything is stable and seems good. i can't really make any voltage reading on the motor board because it seems like it would start a small fire. everything else on that board seems to be just fine (although i'm not too sure about how to test the flipflops properly but all three share the same resistance readings). tried replacing them but they just toasted again. the MJE711 was burnt out and the 3.3ohm resistors were testing high. Naturally i began looking at the motor control board. the motor lookls like its trying to turn over but just moves about a quarter inch but does not spin. the strobe lights are on and respond to an input. the power supply seems to be giving the right voltages. here's whats going on and what i know.Įverything seems to work except the motor. i'm trying to get a broken peterson strobe tuner model 400 working again and have hit a bit of a wall.
