Title: CE-1 part sub
Post by: foozertone on May 26, 2008, 08:18:31 PM
Can anyone point me towards an IC replacement for the TL022 ? Preferabbly something I can get from SMall Bear. They don't carry a TL022.

Thanks

Jeffrey

I mean a chorus Ensemble CE-2. I need the replacement for the TL022 and also for the diode RD11EB. Anyone?

Thanks

Jeffrey

Usually, people use a TL022 in the LFO portion of a circuit.  Common sub in that role is an LM358.

I used a Texas Instruments TL022CP From Mouser in the CE-2 clones I built for a friend and myself and they work great.  Mouser sells them for about $1.25 ea.

The TL022 can be replaced with a low power op amp of the same pinout. The TL062 and the LM358 should both work. They have a higher current draw though so the risk of ticking will increase.

As for the diode, it's purpose is to protect against overvoltage and reverse polarity. The 1N4742A from small bear should work fine, even though it is 12V 1W. It will be larger than the original, so you may have to stand it up.
