Eico 2050: How To Build Manual/Schematic

[mcaddie7]

Was going to post this in Eico forum but though all tube enthusiasts may enjoy it!

Ever wanted to build your own Eico 2050 clone?

I bought one on marketplace today and it came with a full manual. This coupled with the maintenance manual you can “easily” replicate this amp. I’ve seen nowhere online with this instructions so wanted to post.

Very cool intent, you could take it a step further too and upload it to the AK database as well

If so inclined you can send the doc to

ak.pdfs@gmail.com.

And if you do that, please include the schematic. Maybe it's counter-intuitive, but that's much more useful than the assembly instructions for building a similar amplifier.

Thanks for taking the trouble to post these scans!

Of Course, I'll post the digikey cart for a full restore shorty. It includes all Metal film resistors, orange drop caps, and a few other new items. Transformers and pots will remain the same. I'll be ordering in the next few days once I'm done the list and posting the full rebuild / upgrade process here.

So for any other audio historians, I ordered new resistors, caps, ad potentiometers. It came to around $163 on Digikey. This is intended to be a complete upgrade to better, modern components.

Caps were all orange drops, resistors all metal film 1% (apart from the power resistors, those are cement). I'll keep this thread posted as I go along. Now I'll be replacing the small circuits inside the amp as well. Going to order some small circuit boards off amazon and see which ones will fit inside the best. Pictures to come!
