Just logged them from what I can read. They are all as old as the hills it would appear some have bent pins some are in very good nick, there is an EL34 still in the box which I assume is unused.
I've put a ? when the print has worn off the valve.
So this is what I have:
Mullards
EL34 x2
GZ34
EF80 x3
E?80
EZ80 x2
PCC189
PCF80
PCL84
PY81
PY82
ECL80 x2
EF86 x4
EB91 x2
ECC84
ECC83 (just put this in my Blackstar HT-5 and it sounds warmer than the Sovtek one it comes with, definitely less treble)
E??8?
EBF89
EF85
PL81
EF8?
EC?
??84
??84
and 2 with just the Mullard logo visible
Non Mullards:
Tungsram PL36
11 unlabelled of which half look like Mullards
1Phillips Miniwatt EZ80 made in Holland
1 EZ80 could be any brand
Mazda:
PCF80
EF183
6F26
EF85
EF86
ECL80
6 unbranded transformers (some a bit rusty)
1 half brick sized Magtor Manchester transformer
Your trouble with the transformers is you don't know their spec and have no way of testing them, therefore they're gonna have to be sold 'as is'. The one in the middle with the rusty core looks to be the one most likely to be suitable for a guitar amp.
As for the valves, the EL34s, GZ34s, EF86s and ECC83 are all worth keeping (or selling for a decent price). Once again, because you have no way of testing them, its gonna be 'as is'. You'd probably get £60.00 for the pair of EL34s, £25.00 for the ECC83 (though I suggest keeping it), probably £25.00 each for the EF86s and £35.00 for the GZ34.
The other valves are non-standard for guitar amps, so have limited value. I'd be interested in the non-standard valves (i.e. everything other than the ones I'm mentioned above that are worth anything) as I tend to build amps for myself using non-standard 'guitar amp' valves. The PY and PCF prefix ones are radio valves and don't really have any notable value - I've got some myself given as spares when I bought my valve radio.
