The wiring on the octal socket appears to be consistent with a 6SJ7 or similar tube. I am ordering the correct tubes. I will set about trying to trace out a schematic on it. The dial accuracy is OK but not great.

Tugul The distortion was tested across a ohm load. Hopefully I will get it figured out. I checked the sine wave output distortion using my HP Distortion Eioc. I spent an hour slowly working the face plate and chassis back into shape. Eico eiico not play the model number-letter game like many other companies did. Audio Generator A 6SJ7 would make sense and the socket wiring seems to fit as much as I can tell from the pic. Jan 13, The soldering and construction is nice work. Dec Mon 31, The Gear Page is run by musicians for musicians.

The audio cable that came with the generator looked like it was made to check stereo amplifiers. I am working on a right now as well. I will set about wico to trace out a schematic on it. Seller assumes all responsibility for this listing. This was probably a worthwhile mod but unfortunately 2 extra holes were drilled in the front panel.

None of the tubes you listed belong in there. It functioned perfectly last time I plugged it in 10 years ago. Edited to include the eoco The generator was capable of either sine or square wave outputs.

If it was an intentional change, the socket wiring will not match the schematic. Function or Waveform Generator Model: It is marked as and looks like a but must be a later model using miniature tubes instead of octals. Others above have already pointed out that most of the tubes in the unit are functionally similar, so ieco will probably find that the generator is indeed as shown if you re-draw the diagram with the pin-outs of the tubes that are present.

Too funny, love it. Sep Mon 05, 9: Similar sponsored items Feedback on our suggestions — Similar sponsored eicoo. The dial adjustment is broke on the inside and is visible in the picture. I have four other pieces of Eico equipment. Used it as a variable bright cap across the volume pot. May we help you read better. Related Posts.

Oct Mon 24, 5: The output is high impedance and not meant to drive a speaker. The model number describes a particular item that meets a particular spec, eg. That oscillator will drive a speaker if you add a 70 volt line transformer to it. The op just reminded me Eio own a whole slew of those.
