Wavetek Model 271 Function Generator Restoration & Calibration

[edpalmer42]

My 1983 vintage 278 doesn't have a fan, yet the manual, also dated 1983 says it does.     Looking at my unit, the bottom of the case has a rectangular grill rather than the square grill shown in the manual and it doesn't have any mounting holes for the fan bracket.  So mine couldn't have a fan.    Beats the hell out of me!

Here's the area of the Model 271 where the fan connects - J9.

Yea - it's probably a little lonely. Turn it on and look at the pretty blue-green display and generate a signal ...  .

Yes, and my 278 doesn't have a connector or silkscreen or unpopulated holes in the board.  It was never intended to have a fan even though the service manual says it does.

Well, I did. Looks like I forgot how big this thing is

Oh my ... that's a big one. 

Looking at the specs it states it can generate "haverwaves", something to do with the waveform starting at +90 deg or -90 deg. Never heard of or used that term in my entire life. Learn something new around here every day.
