Know what you mean ed, I printed a copy out at work in batches and now have two lever arch files full of RDH4. Don't know how much they are on Amazon but abebooks have some, not cheap though (I suspect the cheaper ones are RDH3 judging by number of pages) http://www.abebooks.co.uk/search/sortby/3/an...

Supertweeter Filter Fine Tuning
I thought I'd got the filter for my supertwatter just right. I'd spent a long time with various values of capacitor finally settling on 2u2. The L Pad attenuation I worked out from an online calculator and the values seemed to work fine. So I finally soldered it all together instead of having messy ...

Ah the eternal 300B debate ~ should it be 2.5k, 3k, 3.5k, 5k, 6.8k ...... This 'ere Madness amp has had 5k amorphous, 2.5k c core and now Bud's 4.545k OPTs. I think quality of the OPT is probably more important. That said Bud is a really interesting guy to correspond with as he talks about minutiae...

Yeah, work really gets in the way of my social life. Actually, work for most of the time is life. Oh well. So, update time. I was hoping to have a bit of time this evening to play but work (grrr) saw an end to that. I did find 10 minutes before cooking tea to dig the old sig gen out and follow Capta...

Tapping the 300B gives a little sound through the speaker, but not the 10Y or 26 as far as I can tell. Putting the meter probe on the anode of each valve produces a little crackle through the speaker. Hmmm. The source works cos I've checked it on a different amp, and touching the first valve's anode...
