well it seems to me that anything from 200-0-200 to 300-0-300 will do; it depends on how you are prepared to play with rectifier, caps and choke(s). I'm using 200-0-200 and its sweet (okay in trioded mode it is weedy unless I'm using sidcup screechers or similarly sensitive beauties; with ls35as I n...

Well Anthony a possible prob. with splitting the PSU up from the amp and using umbilical chords is that you could get all sorts of other interferences and a rising capacitance, and you can trip over the wires! Little 45PP has PSU on board; it is neat compact and sounds very sweet. I can't help think...

groaaaaaaan Simon - you could get answers from 'it doesn't matter through every make of resistor there is to tantalums. Phonostages, it seems to me, are the hardest part of the equation (when young Andrew was talking about headamps, I thought he was talking about headphone amp!) so I would listen to...

meself (for octal) I'd go for less gain than 6SL7 and use 6SN7. I am sure it would drive the 832s

no one ever said that 26 was easy, Phil!

You might want to run a 26 at 480 volts but I don't!

10,000mfd right on the prongs of the valve might help.

welllllllllllll, I've never measured the ripple on the HT as it is a hongker stabilised supply and batteries don't give ripple!

Maybe I can add a little raspberry rip with the wall wart supply.

Can a wall wart PSU play a part in high quality full frequency music reproduction systems, also imparting a full sense of spatial information and realistic dynamic range? ' Switch the phonogram on darling! ' Sometimes I am slow; sometimes grouchy; sometimes I misunderstand myself even and sometimes ...

I go straighttttttttt to '11' !

a coupla hours later, breakfast having been made, eaten and washed up... Well, here's a GM with a GK side by - what is immediately obvious is that GM is 2-3dB louder and this makes a qualitative comparison difficult; so what is point!? The 'tone' of the valves is pretty much the same though. So, I'l...

I'm having a look at them now! 5 amps @ 10 volts (heaters) requires a lovely RCA filament transformer I have but there is no space on this board so although when I began this project (having not thought much further than the input valves, I didn't allow for expansion. So 813s are really the end of t...

So and well so far, I have managed to hear this amp at two local peeps houses so they've done Lowther, Tannoy and my dear old Sabs, so not a bad comparison... By last weekend, quite frankly, I was thinking that all it did was loud, I wsa in the doldrums> But taking the amp out to play at peeps house...

you got it!

just one of them ronken booogahs is better than 100s of mfd of lytics... apart from the dread BGs. Paper in oil is the alpha and omega of caps. You don' need anything else apart from the space to locate them.

And that's why I threw my bank of cheap 'lytics away and went back to film in oil and polyprops; they just were sooooooooooooooooooooh much better.
