Re: Tektronix 561B - is it a decent collectors item?
*If* it all works, its probably worthwhile. (IMO). The 560 series istoggle quoted messageShow quoted text
perfectly usable for what it is. I don't believe the series suffers
from the same HV transformer problem Roy mentioned, I thought that
problem was limited to the 540's...
The caveats, the 3B3 and 3T7 both use tunnel diodes, and the 3S7 uses
sampling diodes (unsurprisingly). I suspect they'd all be difficult
to source if things aren't working...
If you're satisfied with 10Mhz, its usable.... Mine works, and
they're simple enough to be still repairable...
