It is great to see that I am not the only one with a sh*t load of extra tubes.
Luckily, I have a Lamm hybrid amp (M2.1), which only uses
one 6922 tube in each monoblock.
But to make up for the fact that I only need two tubes, I have the following pairs of tubes:
The stock Sovteks;
Two pairs of inexpensive new tubes;
Two pairs of medium priced NOS tubes (Orange Globes);
And, one pair of expensive NOS tubes (Pinched waist);
6 pairs of tubes which supposedly will last me a couple of thousand hours per pair.
6 pairs x 2,000 hours = 12,000 hours.
12,000 hours divided by my average of 4 hours per week (which includes an hour of warm up time) for my listening sessions = 3,000 weeks
3,000 weeks divided by 52 weeks a year = 58 years.
My conclusions from my calculations are:
One, I am not listening nearly enough!
Two, I have way too many pairs of tubes!
And Three, apparently my daughter, who will inherit my gear, is set for life too!
PS Anyone know of a cheap (and reliable!) place to buy more NOS tubes?
