Hello,
I acquired two Lexicon 300 reverbs, and one Lexicon 200. I got them all for a very, very low price in comparison to that which I see them selling for at the usual places.
The deal I made with my wife (our home finance officer!) is that I get to keep one of the Lexicon 300's if I sell the other 300 and 200.
I wanted to see if anyone know, or knows of a source for info on properly upgrading components in these that ought to be upgraded. The all read out the latest firmware version so, I take that as them having the latest chipsets and software/firmware upgrades that were available. I suspect I will mostly be looking at electrolytic caps primarily and/or any other components that are generally upgraded in these units when serviced.
I do know that there were in use up to 3-5 years ago by the owner who was a well known engineer and recordist/mastering guy for primarily pipe organ and symphonic events in the New England area. He was a serious guy and very experienced in all things audio and electronics obsessively overlooking his equipment for the best cutting edge upgrades and improvements. These may not need any servicing at all but, I need info on how to confirm this. He died a year ago and knowledge of this equipment went with him so to speak.
I'd surely appreciate any input that would lead me to a reliable source of upgrades to these items for I did not have any luck finding this. There were plenty of thread and youtube vids on and about the units but nothing in respect to servicing level upgrading and maintenance.
Thank you very much!

Found error code
Hi there, in case anyone is interested
I was led to the service manual that listed error codes for the Lexicon 200.
After successful triage at home, it began making sound astounding digital sound and popped an error code of E95. The code showed a list of one "primary suspect" and 5 "secondary suspects". I ordered the chips and was delivered all except for one, an SN74LS14N (Hex Schmitt trigger low power shottkey inverter).
Unfortunately, the error code still shows up. So, I'm banking on a prayer that the replacement of the single backordered chip would fix the issue. It just arrived last night. One fellow on line had a very similar issue to mine, and was E96. Same secondary suspects with a different primary. I replaced the primary suspect that he had just in case it was related. He even posted a sound clip of this weird digital noise, and it was very close to the same sound I was getting.
So, if this last chip doesn't make the fix, I'm facing an uncertain road of trying to diagnose the problem with my Lexicon model 200. Which is too bad because someone wanted to buy it but, of course I cant do that until I have it functioning the way it suppose to,
On goes the saga of the weird sounding Lexicon 200. Please wish me luck - I'm going to need it.

Hi Markw4,
At my work we just got a handful of very expensive new scopes. The lab supervisor has put me on the list to get one of the old Tektronic scopes that will be leaving the lab. They are relatively old (still have floppy discs) but, theres 4 of them (4 channel, 300Mh) so I"m really hoping to nab one of those.
Then, I will take to the service manual and follow the directions to see if I can get to the source of the issue.
I'll come back to report my findings should I make a finding, and I'm very much hoping that happens!
Thank you,
Phil Donovan

Hi Phil,
Here's hoping you end up with scope too!
Besides the service document I found there is a also a published schematic. Don't know if you found that too. If not, maybe I can post it or provide a link.
With those two documents, a DVM, and a scope the odds of fixing the reverb should look more encouraging.

Can use schematic
Thanks again Mark,
Sure, if you find a link to that schematic that we be great if you could leave the link.
I've got my own DVM and signal generator, just need that scope and the schematic would be great.
I have a pretty good handle on the functions of most all the logic chips which appears to comprise a very large number of the IC's, but there are ROMS and processors that at this time elude me. But, perhaps a deeper look into the service manual will clarify where and how to look for the sources of problems.
Alrighty Mark, thanks, and if find that link, please send it along! Much appreciating the offer.
Best,
Phil

Lex 200 schematic
Hi Mark,
thanks so much, got the schematics, looking them over already. Quite alot to look at but, the more I look at it the smaller it gets, right? Ha, right!
Appreciate the send, now to get that oscilloscope and get to work ,
Thank you Mark,
Best,
