After having a minor problem with my EICO HF-61 pre-amp, a search was initiated to find info. None relating to the EICO HF-61 pre-amp or the HF-30 power amps, of which I have two. The original had 8 tubes and the latter had 7 tubes.
The best result from that search was this forum but unfortunately, little to no mention of the above units was found. Having these units for about 20 years and now having to remove them from the audio system to fix the above mentioned problem, an aggressive search into my data stack revealed some interesting data. More detailed analyses was made of these units with the intention of placing that data here but that collection became rather large.
Uploading all this info into this forum seemed to be a daunting task considering my years of experience using Microsoft's Front Page Web Management Tool since 1997. So, I set up a web page in my website.
Here's the link to that page. https://www.ln271828.net/an_eico_odyssey.htm There is a plethora of data on the performance of the three units in my posession. This data can Tbe found about half way down the page in the section titled, The technical Stuff.
Hopefully, the data here will be useful to someone. There are two original schematics, one for each of the 7 tubes and 8 tubes units. There is also a copy of the Sam's Photofact for thr HF61.
