I've gotta say, the innards of mine don't look terribly robust. The pots, switches, connectors are all pretty cheapish, and there's very little clearance between the bottom of the board and the case. It wouldn't take much to knock a connection loose or short something.calaverasgrandes wrote:I have to say I have broken 3 effectrons.
never could find anyone to fix them.
No idea how I broke em.

I used to run one in my FOH rig and also had one in my bass amps effect loop. I loved how it sounded on vocal delays. Dale from Acid King (also Melvins) complemented me once on the vocal sound I got with that.
On bass it was a neat flanger, plus you could hit repeat hold and walk off the stage as the drummer kept smashing into oblivion while your amp is cycling up and down the repeat.

the red tube is the battery for the memory, which on mine still works.
i think it has been replaced a few times on this unit.

Don't know if this has been posted yet either:

Basically, you're looping the data stream from the RAM back into itself to create and infinite loop, but you're also piggybacking another set of RAM chips, so you can send data into those as well and create longer loops.
I think the procedure would be the same for the 1024. I'm going to try it with my 1020 at some point. Finding those RAM chips may be difficult though. May have to scavenge them from something else.

Delta Lab Effectron
I'm wondering if anyone here can give me some info. I have an effectron, 1024, not the effectron II. I am currently trying to get this unit up and running again. I am not at all sure what is wrong with it. I have schematics but they are for the Effectron II. Apparently there are some differences between the effectron and the effectron II as looking at the schematics and checking values, particularly on resistors there are some differences. Does anyone here have the schematics for this model. Effectron ADM1024? So far I have swapped out the two large capacitors in the power supply section given that they are over 30 years old. Have checked some of the other components. What would be particularly helpful is the parts list for this unit. Mfgr. frequently include this in the user/maintennance manual. If anyone here has any info it would be most appreciated. Thanks

scroll down to read a letter from Richard E. DeFreitas , founder and creator of the effectron line.

Perhaps even more cool is that Chuck Fertitta checked in there with some advice for getting units working again...
"I worked at Deltalab Research back in the early 80’s in manufacturing and service. If my memory serves me correctly… check the pots’ connections to the PCB. One or more pots may have a hairline fracture, thus breaking the connection. This was a typical problem we found in repairing the units. To make the unit(s) more “road worthy” – try replacing the pots and soldering wires from the pots down to the PCB. A second item to check would be any of the input amplifiers (op-amps). May have blown due to static discharge.
Also, the Effectron was the initial model with 1024MB of memory. When we later expanded the line – the Effectron was rebranded the Effectron II. The Effectron II included upgrades to improve the sound, thus the mismatch in parts."
Good luck!
Chuck
