Ibanez Tube Screamer TS9 Not Working

I still have to dig into the flanger flatrockmobile sent me.
Still on the list, hope to find the time before spring.
 
My friend Craig has a couple 808's.

I am not sure too much of the Historical details or markings/various resistors, caps etc that distinguish early from reissue ones, but am curious how to tell how old this one is. Mine does have a Maxon marking on the battery door, Made in Japan on the bottom cover, but has that C E marking on it too. Somehow my cluelessness makes me think stuff with that marking is a new type thing. Although, I am old enough to remember the 80's as being NEW.

I will try getting a pic of the back for ya.
 
Oh boy, Sysco got me thinkin and lookin. HA, mine is apparently a miniature anomaly as it has the Ibanez board but Maxon battery cover. It's definitely a resissue

I don't think so. Maxon originally made those for Ibanez. Your circuit board looks old.

Does the bottom have a black label?

What's the code numbers on the main IC chip?

Around 1982 until 1985 the Ibanez pedals were repackaged and the 9-series of effects were made. The most popular was the TS-9 tube screamer, which is almost the same as the TS-808 internally. Externally the on/off switch grew to fill about 1/3 of the effect. The main change in the TS-9 circuit is in the output section. This caused the tube screamer to be a bit brighter and less "smooth". The Edge from U2 uses a TS9 for most of his overdrive tones, as do countless other famous rock and blues players. In later years the TS-9s were put together with other op-amp chips, instead of the JRC-4558 which is called for in the schematics. Some of these sound BAD, especially the JRC 2043DD chips. Many used the Toshiba TA75558 which was continued on the reissue. If you have an original TS9 with the 2043 chip, our 808 mods will make a huge difference in tone.

Sysco, mine has the TA75558 chip, Silver sticker on back with CE marking

I had the first-gen TS-9, bought it brand new when they very first came out with the "9" series pedals, in 1982 I think. Long before there was a lot of hype about them. Kicked the living crap out of that thing for close to 20 years before it failed. Got the reissue, this one:

Ibanez TS9 Tube Screamer Overdrive Pedal

And to my ears it sounds exactly the same as the original one. I know there is debate about the 808 vs TS9 and Maxon vs Ibanez thing, but for $99 its a hard pedal to beat.
 
Ok Chilli, that diode will (I imagine) be the "reverse polarity protection" diode that you indicated on the power supply schematic. It should be connected between the 9V+ rail & ground & its job is to protect the circuit should a power supply of the wrong polarity (center positive) be plugged into the DC socket. It protects the circuit by failing (shorting), the idea being it is much cheaper & easier to replace that diode than fried circuit components. While on this subject, using a 1000mA supply cant hurt anything as current is "drawn" by the circuit, not shoved into it by the supply. Now I'll go back & properly read the new posts. Cheers
 
Thanks, Ivan read away, LOL

This explains a lot in so few words. My suspicion is almost confirmed if I understand the picture on the 2 DC power supplies I have to be an indicator. The Danelectro is the same symbol as the back plate of the TS9. It shows center - AC adapter center neg.GIF

My 9V 1000 mA is as you say. That DC power supply shows a + center.

I sure do learn my lessons from my lack of knowledge. Somehow I learn way way way more than I ever expect, all due to simple details like not knowing different supplies have their polarities reversed and I need to be extra careful to make sure both the device and the power are an exact match.

Yeah. You have to be careful with the power supplies. In every other application I've seen, DC power supplies have a center positive. For some reason, guitar effects pedals require a center negative.

BTW Chili, is your TS an original production run... not a reissue?

I am not sure about that, his board say Ibanez not Maxon. All the first Tube Screamers had Maxon boards. Mine is a Maxon board and does not say Ibanez on it anywhere.
 
Ok I made the last post before reading the entire thread. Chilli, BTW I have a Dan Echo pedal also, I love that thing. To me it is the best Echo out there except the knobs are sorta small.

On a side note... I have a '79? '80? Ibanez Analog Delay that I bought brand new. "Maxon" all over the board!
