Yes please, but collection may have to wait until after lockdown.

You're welcome, that's fine, or can leave it in a safe place outside my house somewhere if that helps.

Is that the one that has the bias oscillator frequency ,close to or at 200khz , we had a customer who wanted to record the cricked on LW but when he switched the recorder to record it wiped the station out , Happy days . Mick.

Does not appear to be, the Technical Data in the Beocord 2000 Service Manual lists 100kHz for the erase frequency.

Hi @Michael Maurice,

hope you are well, any chance you could think about collecting the tape recorder now.

Thanks

Probably second harmonic ; 2 x 100kHz = 200kHz. Bias frequency is 120kHz in a Revox.

On most tape recorder bias oscillators the fundamental frequency looks very clean and stable when viewed on an oscilloscope, I would say that it would be difficult to see/measure any harmonics without the use of a Spectrum Analyzer.
