Sorry, for some reason Im not able to reply to the messages so I'll
have to strat a new thread. My hat goes off to Iain & Mike your
knowledge is something else and Im learning loads here!

Ive not printed off the Mullard pdf as Ive got a similar one from
Svetlana (although much shorter) but the basics are the same. At the
minute Ive settled on 35mV, as applying the 70% rule seems to point at
this figure, although getting the exact voltage is the only real way.
Anyway, with Iains calcs it all means that the tubes are running at 14
watts so Ive a question on this. The amp is quoted at 40 watts per
channel, I presume that this is at full bias and seriously loading the
tubes. How does the relate to a SS amp? is a quoted 50 Watt SS
running at this or does it have a bias??

Anyway, the amp is sounding superb, the svets & mulls are running in
nicely and with my simple AE Evo 3's I can honestly say in the 5 years
Ive been into hi-fi Im happy, and its cost me little cash! Funny thing
is, as Im of a time after valves my mates, who have never seen them
before, think theyre something new as it sounds so much better than
anything Ive had before!! I dont like to tell 'em the truth ;-).

On the tweek front, Ive no plans for the minute exept put a 10Ohm
resister in line with the led as its too bloody bright and Im too much
of a tart to be happy with black leccy tape over it!!

Bugger that, just rub the LED over a bit with a blue felt tip pen! ;-)

I like the idea of people thinking that valves are something new:-))
Tell 'em the truth, they are listening to 100 year old technology which,
in the opinion of many, is still out in front:-)

Is the LED powered from the heater circuit?
If so it may have a 330 Ohm resistor.
I find a LED drawing 20mA is far too bright, and distracts from the
glowing bottles. Adding 100 Ohm will not make much improvement.
I use 1k2 . That's mellow:-)


Cordially,

Iain

You can say that again and it's an opinion that is steadily gaining ground,
according to the comix!!!

(I'm almost tempted to count the pages featuring valves in the January 2005
HFN I've just got - must be getting on for 50%!!)

Well, you can see the LED in question in this wobbly snap:

which has been on my Show N Tell page

http://www.apah69.dsl.pipex.com/keith_g/show/show.htm

for a while now (along with a load off assorted other snaps - some related
to these amps) and I reckon you've got to look hard to spot the LED with all
the other nice little glowing bits beaming away!! ;-)

OK, make that two goes with the felt tip then......
