I pulled out my old waveteck and found it was the same one in this video. I think it's all original. I'm going to test it the way you did and see if it distorts a high side.
I was on the fence about getting one of those old Waveteks. The mechanicals are solid and the looks are gorgeous. I’ll get a couple and upgrade them a bit. I got a couple AD639 laying around. Those are sine converters (and more) extraordinaire.
If ever I have an issue like this with knobs that do not match, I will always make the even number match, where possible and make the odd one different. It looks much better if the black knob is used in the middle and the silver one moved to to be symetrical with the other four. This is not always possible, of course, but makes a much better appearance when it is. 😃
so are so right :-) but the range switch is a bit hard to twist, this new one make it easier due to its different design, from a distance it is quite allright now, at least a whole lot better than what i started with :-)
Thanks for posting this. I recently got a Wavetek 110 and had similar problems, including a manual I downloaded that similarly doesn't match exactly. I had stability problems until I cleaned the two pots (mine has just two) by prying them apart. They reassembled and work fine. Am I reading your scope wrong, or is your sinewave more negative than positive? I had the same thing when using the variable jacks but not the fixed BNC. I even tried to adjust it but ran into limitations due to the manual being unclear -- and because I can't get at the adjustments when the unit's assembled. Maybe I'm expecting too much, but I assume we want the peaks to be equal but opposite. BTW, if I were you I'd swap the vernier knob for the shiny one so at least it's symmetrical.
Been enjoying your vids and have subbed ! but this is an older video so I hope you read this. I have the big brother of you 110 mine is the 112 ! mine is the 'Triggered VCG' mine works but has dirty pots and I will replace some caps. I have a problem that at the top and bottom of the waveform (Sine) I have a very short but quite high 'Spike' and after you pointing out about a little blip at the top of you wave it got me thinking !! and then you pointed out that it works by " ramp up and ramp down" so maybe it's overshoot or something ! But the biiig problem is I can't find a 'riser card' for the unit in order to get to the adjustments ! And I can't find a source of the gold connectors that are used so I can't make one either, have you any thoughts please ???
i make riser cards from old stuff that is un-fixable, i keep old-dead units until i have pulled all useable parts from them, this way they donate their last life, to help other units live longer, (the cycle of life in my world) I hope you dont expect to get the last tiny spike away from the sine, it is not possible, it is a needed sideeffect from the way this one works, I recommend contact 61 for your switches and pots, I read all comments on all videos, i wish you the best of luck with your wavetek

Well I know what I'm going to check on my Wavetek Model 185. It has some similar looking problems with the sine wave.
I am always super happy when details in my video can help others to find the error fast and easy

@@TeardownOZ2CPU Thanks ! Do you know the name of the gold connectors that are used in our instruments please?
@@andymouse sorry cant remember, some of them got a tiny logo on the edge
