    Eico HF-89 Replacement Chassis?

    Reaching out to the Eico-verse! I purchased a nice HF-89 that was shipped to me. Unfortunately the packing job was pathetic and the box looked like it was delivered by the American Tourister gorilla. As you may suspect, the chassis and transformer brackets were at odds and neither came through...

    HF-85 Purchase

    Recently acquired a HF-85 that has been worked on previously. It sounds really good but is a train wreck cosmetically. I’ll probably break it down, remove the rust and try restoring the original finish on the cabinet. I’m evaluating what has been done and what I won’t to do while it is apart...

    Eico 2050 - Adding Loudness switch?

    Hey all, I have an Eico 2050 which I’ve gutted and installed the nicest parts with tightest tolerances I could find. This thing sounds lovely. However, I’d like to change the hi pass filter switch on the front to be a loudness switch for lower listening volumes. Any tips or tricks? I could...

    DIY EICO HF-87 Clone Ft. David Gillespie's EFB mod

    I had a go at building an HF-87 clone from scratch. Wound the output transformers from 3/4 stacks of microwave iron and 3d-printed nylon bobbins. Power transformer was wound from an old HIPOT transformer with another 3d-printed nylon bobbin. DIY walnut cabinet.

    60's Eico vs 90's ASL

    So a little while ago I bought a pair of Eico HF-14 monoblocks in nicely restored condition. They use el84s and put out about 14w each. Obviously they're not the last word in fidelity but boy do I love listening to music with these. I believe I've caught the tube amp bug. I'm looking to get a...

    Eico HF 81 VS Dynaco St 35 DG Style?

    I have yet to find any EL 84 stereo that sounds as good as my rebuilt Eico HF 81, I've read such good things about the St 35 using Dave's boards and wonder if anyone has heard both the modded st 35 and hf 81 and can compare them. The Eico is so musical sounding and sounds way more robust and...
