Thanks everyone who sent me offers and information on the computer. I think it will be destined for sale on eBay where I can let the market set the price..... the offers were so far ranging that I feel that it would be the best way to sell it and a search revealed three others that had sold there recently. I'll include a copy of email I sent to several who were interested in it's actual condition after I had a chance to look it over. I brought it home last night and checked it all over as mentioned below. I hope to have it placed on eBay this weekend unless I break down and sell it to a reasonable offer off the net or at a ham/computer fest I'm attending on Sunday. There is a pic of the computer at http://www.vbe.com/~badger/bc/ec1a.jpg Again..... thanks for your interest and all the information. de Mike Melland, W9WIS <copy> Last night I took the EC-1 and the other instruments I purchased at the surplus sale home. I cleaned up the EC-1 and checked the tubes, caps and all the circuits. I applied a little Caig Deoxit and with a bit of time and care and was able to free up all the potentiometers that were stiff or frozen. It appears to have been a factory built version that was sold to the college...... very nicely built and laid out. The cabinet has a few small scratches... easily touched up... no dings or dents. The rubber feet are still in place on the bottom. Inside, while quite dusty when I received it has been cleaned up and is very nice. Tubes and Caps and all wiring and pots check out fine. After checking things over it went onto my isolated variac and was slowly powered up..... lit up fine, adjusted B+ voltage.. was still right on the money. Used the manual to set it up and adjust the individual amp balance, all three ranges on each amp (100,10,1) balanced just fine. Everything seems to work and adjust properly at this time so I assume it's quite usable. The manual I have for it is an operation manual..... apparently there is a construction manual that would have come with it if it was a kit version as well. Also has three of those little clear plugin units with a cap and a precision resistor....
