I've seen poor design before, and I would've put a zener across their power supply if this thing turns out to work at all.Įdit: the 470 ohm resistor will drop sufficient voltage at only 9mA total, and each IC draws an average of at least 10mA, so that's the explanation why it lasts. I doubt any other version or type would stand 25V (for very long). Expect to pay around 100 for the most popular models of pedal tuners. The lithium battery lasts up to 18 hours. The tuning modes include Polyphonic, Chromatic and Strobe, and the range is from A0-C8. Reference pitch is available between 435-445 Hz.

If you Google the IC and take a look at a pdf datasheet you'll see an image of the IC. It features a strobe mode with amazing plus or minus 0.02 cent accuracy. If you connected those caps to ground or in parallell it could explain the overload. The resulting total capacitance is thus half of each section (5 uF) and it also becomes a bipolar capacitor (meaning it can stand Alternating Current).

That makes it a series connection of the two 10uF caps. In the diagram the wires are only connected to the upper two terminals, nothing to the common terminal.
If you disconnected the ground wire and measured infinite resistances to the frame then that (together with the other equal resistances) is a good sign that the motor is ok. 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 don't really know what it should look like or if it could be frying transistors. on the scope the signal looks like a spike up and then down. If you would like more information on one of our inventory. The other thing i'm not sure about is the signal coming in from the tuning circuit. Due to our high turnover rate, this catalog is not guaranteed to be accurate.

however bot coils are not open and have the same inductance so i'm not certain how to confirm that its dead. What i'm considering now is either that the motor is dead. 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. The Peterson StroboPlus HD tuner is the highest resolution strobe tuner with Petersons largest illuminated display ever featured in a traditional strobe. If you require service, please open a support ticket and return the tuner for repair. Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration. Naturally i began looking at the motor control board. Strobe tuning display with +/- 0.02 percent precision Running time of up to 18 hours and power-saving auto-off feature Adaptive display for easy reading regardless of orientation Ideal for acoustic, electric guitar, and bass guitar Flat tuning and capo mode as well 5. Generally, your tuner will not require calibration and should remain perfectly accurate if it has not been damaged.
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. The Snark ST-2 looks attractive (for features), but then the Snark HZ-5 is said to be for "guitar, bass, and violin", and the stem's ball-and-socket joints appear to be more robust.Hi everybody.
I don't care about the metronome function.

I'd be happy with just a single chromatic mode for ON/OFF switch convenience, low-frequency sensitivity (at least to low E on an electric bass), ability to calibrate the pitch, and maybe a Hertz frequency indicator. StroboPlus HD Features and Specs Accuracy: 0.1 Cents Built-In Microphone Note Range: C0 - A8 Note Selection: Automatic or Manual Concert A Setting Adjustable from 390Hz to 490Hz Frequency Response Range: 16. Something both are weak at is tuning low notes, like around 3rd fret on the low E string of a guitar and lower. The annoying part is that to turn it off you have to press the button 5 times. I also have a small older Peavy tuner for a backup, but it it has 5 different modes - chromatic, guitar, bass, violin, and ukulele. I have a Snark SN8 tuner, but since getting stepped on it's reluctant to turn on, and when it does light up it displays two bars.
