Fozgometer

I love my Hagerman Piccolo step up. Just a simple twist of the knob and I can select from 6 different loadings. So much nicer than soldering and de-soldering resistors inside a box, and the sound is transparent and musical too. Thanks for a great design Jim,

I was having problems with the accuracy of my Foz, which was still very new (purchased from LP Gear). I tried to calibrate the unit using the test tones provided on Musical Surroundings web site, but couldn't get it correctly adjusted and sent it to Musical Surroundings for service. The service manager, Mike Fajin, told me that my unit was severely "out of whack", but he was able to accurately calibrate the unit using a special signal generator built for MS by Jim Fosgate. So, if you have a Foz that's not accurate, or you have problems with calibration, you might want to send the unit to MS.

Sdcampbell, that's great information. I used the Musical Surroundings test tones to calibrate my Fozgometer and it went smoothly and the Foz works well for azimuth adjustment. But if the unit ever seems to be "out of whack" and the test tone recalibration method doesn't work I'll know to just send it in for service. It's nice to know that the unit is so easily restored.

Regards,

How do you define "whack" and whether your Foz is in or out of it? It's based on a subjective impression, is it not? Unless the azimuth is so askew as to be impossible.

If it can't be calibrated to the test tones, it is out of whack. Nothing subjective about that.
