Hours Run Meter for valves

[bob4333]

What you need is a 'run time meter' or 'hour meter'.
Here are some links:

The last one on ebay is a comparison so should give good food for thought.

You would need to power it only when the amp is on, via any switched mains outlet would be the easiest way.

Yes, I had looked at the mains powered options and the ones you quote look pretty good. I was hoping to find something cheap/plasticky/AA battery powered that doesn't require plumbing in or major surgery. Something that doesn't turn into a major project in it's own right if at all possible.

Next time I break my system down for cleaning I'll take a look inside the power supply and see what in theory could be done. I'm not going to get neurotic over counting the hours - but thought it'd be good to do if it could be done simply.

Thanks for the links.

Icon Audio are good people I understand and are readily available for advice on valve type and replacement. I'm shooting in the dark here, but mil-spec valves may possibly have a longer life - why not ask them? ECC83's are common as muck and there are still many varients you could sucessfully tery I think. Again, as the distributor/manufacturer...

I agree about Icon Audio and have spoken to them in the past - refreshingly helpful whether you're buying or not. At present I'm just looking to get the performance back that seems to be edging away - which is why I went back to the manufacturer for replacements.

I've just found a battery driven 100 hour timer for £6 delivered so will start with that. Still need to manually track every 100 hours though but it's better than continually writing down start/stop times. http://www.ebay.co.uk/itm/2608369067...8#ht_770wt_969

There was a 1000 day timer direct from China that I thought I could make work until I tried to read the instructions.............
