Lexicon Prime Time testing fun

This time, i show you some knobbing on a Lexicon Prime Time i just repaired. The unit was in a horrible condition when it came here, the main transformer was completely missing, the unit was ripped, lots of ICs were missing, lots of electronics was broken, some PCB traces were burned off. It took quite a while to get it working again, but after all, it's a lot of fun to play around with the delay time modulation and the feedbacks of the two delay taps.

DISCLAIMER: because of legal reasons and very limited spare time, i can't help you with your electronics problems, so just don't ask - your questions are likely to be ignored.

Hi there, very nice video! I have a PrimeTime and have the same problem, transformer is missing completely. Where do you get that blue ones for yours? Or how do you know which one to buy? Thank you,

@santifmoreno It's not my unit and it's too long to find out where i ordered that stuff. I'm quite sure it was one of my preferred components dealers here.

Which one to buy? If you ask me this question, you should not try to fix this unit on your own as the fun really stops at mains voltages and you need to know what you do - which also includes knowing how to dimension transformers after determining the needs. I can just dig out the old photos, but everything you do then is on your own risk!

Very nice!

People who take the time to repair units like these are very worthfull.

I myself use the Eventide H949 a lot which breaks down quite often.

That's also a unit people say of its too difficult to repair.

I think its a matter of time and effort to keep these kind of units alive.

@MatthewleBlom It's like fixing old cars. From an economic point of view, it doesn't make any sense, but it's the fun to just do it and some gear just is worth being fixed. The commercial world doesn't do it. You usually don't want to pay several hours to get such stuff fixed. Only hobbyist are crazy enough to spend all this time :)

hello .. i've got a lexicon lxp 1 acting strange when using small room preset (mix goes from dry to wet) you think somebody can restore it nowadays? i really love it

[MusicMiK]

I'm quite sure there are people around you who could have a look at it. In worst case, you need to pay 20 EUR or so for the schematics, and maybe some workarounds for no longer available parts are necessary, but as you see in my video - this Prime Time was ready for the junk pile when it came in. And i didn't do any rocket science on it :)

very nice demo

I worked at Lex while this was being designed and manufactured. Yes, it's all TTL logic. If you want to really freak, look inside an original Lex 224

Excellent demonstration ... now I will buy one!
