Good this isn't it! :) So if I turn the power TX thro 90 degrees it'll be feeding an unrectified 50Hz sinewave into the choke and if I reorientate the choke back to where we started it'll be feeding 100Hz ripple into the other OPTX. Looks like I can't win either way with this layout. :( Good job the...

There ya go!

Yep your right Andrew I'll rephrase the previous. The trannys are positioned so that the lams are mutually at right angles between the mains TX and the output TXs. You can't see the OPTXs as they are in the boxes but their lams run right to left whereas the visible TX and choke run front to back. Mi...

Ah well....you see The mains tranny is positioned so that its coils are at right angles to the coils of the left hand output transformer in the box, now I didn't want the choke interfering with the right hand output transformer so that too is at right angles to the right hand output tranny. Unfortun...

A bit of progress on the 46 Amp today. The case has been built and all the hardware mounted. I'm not doing any more on it tonight but it's ready for wiring. I've still not quite finalised the design details yet but it should work OK. What it'll sound like is another matter :wink: Here's a couple of ...

Just come back from a weeks holiday in another Country. It was called 'North Lancashire' I think... :wink: Scoured the Chariddee Shops and turned up.... Oooo....been looking for this fer ages in tippermost top condition. Had it on a copied cassette and played it til it died... Was(Not was) 1988 'Wh...

The vinyl is fab - all sorts of detail and things that are just missing from the antiseptic clean sound of the CD. Mind you I only like one track. very interestingK! Ha Ha That's a larf Andrew! I have the vinyl too. It was horrible on my Linn/Naim system. Ms Tikaram's sultry vocals sounding like a ...

Hi Philip "Well spotted that man" What I tend to do when building an amp is to do the mains wiring and valve heaters first and test them with the valves in to make sure the heaters are all functioning. Next comes the power supply, rectifier wiring and caps. After that I insert the rectifie...

Hi Simon.

I think the Linux guys will probably need to chime in here. I can't really see it being a drag and drop installation.

Hi Andrew

I have a pair of Hammond 125GSEs that can be configured for 10K primaries. It looked a bit more linear with 10K when I did the curves but I'll switch it to 5K if power is an issue.

Steve

This one uses triode strapped 46s driven by paralleled 6N1Ps.

I need a backup amp to play with so this one should prove interesting.

As usual here's a schematic to ponder.

Hello Dave and welcome to Audio-Talk

Steve

If your speakers will do `Young Person' well, it will cream Prodigy etc etc. But it doesn't work the other way round. You're right there Andrew but I sort of arrived at that conclusion from a slightly different direction, in that I used quite a lot of old sixties pop and soul recordings on CD to tu...

Well that worked very well indeed

I've started on Vaughan Williams "A Sea Symphony" That'll sort out the big choral stuff; "behold the sea itself..." and all that jazz. Scary stuff!

Steve

Hmm...... I've just fished out my vinyl copy of "Young Person's Guide to the Orchestra" It's on HMV Greensleeve, recorded in 1959, packaged with "Peter and the Wolf", narrated by Michael Flanders, plus Saint Saens "Carnival of the Animals" I'll give it a spin and see wh...
