Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

For those interested

Attached are links to a schematic and a view of the bottom of the Eico HF81 chassis. This is the worst electrical design I have ever seen! No Ls in the power supply, .275 ma plate current in the 12AX7s, 40 volts on the plate of some stages, etc. Looks like they were aiming at a very high tube count to make it appear to be quality. It makes the Dynaco ST70 look great!

It's realy straining credibility to believe that some 10 gauge wire can make this thing sound good ...
