Hi, IB:
Many years ago, I picked up one of these nice fancy hourage meters, the type with rotational numerals showing up in a window, cut through the face.
I used it to track hours used on my Marantz tube amplifier, an 8-B.
Then, I finally just put it away.
But, those devices, many of which are still being offered through various surplus electronics outfits, can be inserted in-line with the power cord of any device and will inevitably keep track of total hours used when the device is operated, that is.
The URL below just shows a couple of more modern versions of the hour meter, some of which can be panel mounted, some not. Check it out!
Of course, it will not differentiate winding time "off-the-heads" from hours "on".
And, one further little observation: on the Panasonic SV-3700 and SV-3800 DAT recorders, there once were hour meters on the back of the recorder, so one could more or less determine total hours on the rotational heads. I think Panasonic may have removed this feature on their later models, but it was on the SV-3700.
And, ask yourself why high-end tube amplifier manufacturers never built these devices into their products? Why, it would make the user nervous and apprehensive about the longevity of the tubes in their gear!
There you go!
