Same here, minus the metronome. I don't find music to be a compelling
need in the darkroom.

You sound like John Douglas.

David, did you post a question to me about older Kodak
enlarging lenses? If so I can't find it again.

Last week I made test - bottle of Rodinal used last time 5 years ago
(so it has 6 or 7 years). 1+25 - still works without any problem.
I tested also D-76 1+1 mixed in Sept 2006 - works not so good, but it's
still ok - without direct comparison no visible difference.

And never ask such questions - shot a few test frames, cut film
and develop it. It costs a few cents, but can save your negative
if something will go wrong with developer after wrong storage.

In low dilutions yes - but I don't recommend it.

After Rodinal don't use acid stop bath - plain water
works ok - I use 3 water changes in 2 min.

Greetings

I have an old "boom box" with tape player - preceded CDs. I put a layer of
duct tape over the pilot lights so they are very very dim. No problems with
light.
I find that listening to music helps me relax and avoid the temptation to
rush the timer on the chemistry.

Metronomes are handy for counting intervals, but I mostly use digital "egg
timers" from WalMart for timing stuff in the darkroom. The gentle beep can
barely be heard over the boom box at modest levels.
