Don't think what Mike or I was saying conflicts they are just additional points. Can't say whats best, personally I would use one supply for the output values, other for the driver valves, tie them both to ground each with its own centre tap. Well, actually, if I was breadboarding it, I would build ...

Has anyone tried them with the grids/anodes/cathodes paralleled as SET ?

If its on the net it must be true, and possibly posted by someone who hasnt heard of plate curves

Hi,

Not sure if there are many on here that are into such kit, but doesn't hurt to ask. Also at the moment most of the user base is in the UK. I assume from your pricing that you are not?

Available on CD, where This may be something like. Can make as much of it as you like :-) http://www.lurcher.org/~nick/sound.wav #include <stdio.h> #include <string.h> struct wav_header { char ckID[ 4 ]; long cksize; char WAVEID[ 4 ]; }; struct wav_format { char ckID[ 4 ]; long cksize; short wForma...

1:10 pulses of 10Hz square wave at 0dB with ping added at -15dB, that should keep it busy.

Use it to make a shunt regulator for the 6dn7 amp?

Though because you have a 3dB/Octave slope on the graph its a bit (possibly) misleading, the pink noise is equal energy per octave, so the actual peak levels decrease as the frequency increases. I guess pink is better at this that white, in that white has increasing energy with frequency so will pro...

I think you would be best asking that of HFW. I actually bought a copy of the mag this month (got it over with for the year), and there was a interesting editorial about how just because something is in print it may still be wrong. Maybe this is a bit ironic, or maybe this text is wrong, who knows :-)

Depends. being 20v below the cathode is often as good as 20v above the cathode. Often cathodes are 20v or so above ground, so its already done.

I will take a look at it, again, I have moved the server, so it may need some tweeks.

Yep, we used to have a goldfish (now sadly departed) that would headbutt his tank every evening at about the time he/she would get fed until someone took notice and fed him/her.
