Yup, 6EM7 just didn't quite go loud enough for me, that was pretty much my only gripe. I listen to a huge range of musics and some of the hard funk/pop/dub stuff just made 6EM7 fart out. The only other thing I found was when I was doing side by side comparisons I eventually worked out that SE and P...

This week's violation is next week's recycling Dave. You're on the slippery slope now. :wink:

Good to hear that Ortofon are giving you good customer service Clive. I got my Kontra B before I heard of your woes. So far there's no skew, and although it does appear to ride a little low for my liking it does just clear the record surface. As mine came from Hong Kong I don't know how much support...

Thanks chaps. I figured that I may get some "AC" reading because of lack of smoothing, but figured this would be half of the DC voltage, say 6ish VAC. How it's 15.5V I don't really understand though. Neither do I understand why changing the probes round should make a difference - surely it should ju...

Spot on Nick. Changing the leads around on top gives me 15.5VAC and 11.4VDC. Switching the leads round on the underside has a similar result - no AC. Why should changing the way the probes are connected have an effect? Is the meter dodgy?

Schottky bridge problem

This seems the most appropriate place to post this, so here goes. I'm playing around with a 7.5V tx with the aim of DC heating the phono I've been working on. (The mains tx has a 6.3V winding which I have been using but I want to use this for the series reg valves for the HT). I thought I'd get the ...

Hi Shaun, Thanks for the pointers on the reg, that's really useful. I popped over to Steve The Shadow's on Saturday and as well as hearing his new PP amp and the new-super-improved Metronomes I scored a borrow of JJ EL509s and 6080s. Thanks Steve. Thought Steve's combo sounded really good - a PP amp...

How's yours sounding Simon, did you get the instability sorted in the end? Dr Nick got the instability sorted out - lack of gridstoppers on the C3g. :oops: It sounds pretty good, it's really fast, and plays tunes in the bass, but doesn't have as much detail as the KRs perhaps. To be honest it's not...

Looks like you might be ready for Witham Dave? I'm hoping to get be able to make it for a weekend of beer and hi fi - I could bring my 2A3 version to compare perhaps? I'll even bring my bestest RCAs, sadly only dualplates. I saw some nice looking monoplates on ebay t'other day, but at 600 dollars I ...

Yeh, that makes sense. I was coming to that conclusion when I did the sums.

Thanks Nick, I think I understand that. So thinking of the 470nF Russian PIOs I have, to bypass them with a 10nF silver mica I should use 39k to give me approx 400Hz. 39k seems quite large - might this have an effect on the sound? I think I have some 4n7F silver mica too, maybe I'm better using thes...

Would the 560R be the same for the coupling cap in my phono, or is 56R right in that instance?

Hi Steve,

Good point about the current requirement of the 6C33C. I think Nick did say that they were AC but they were so quiet I guess I forgot thinking they were DC. There's a certain reassurance to a little hum - at least you know the amp's working :D

Ooooh, that's tempting. Are the heaters AC, I can't remember? The hum was pretty impressive if they are.

Went over to Nick's last night for another fun evening. Listened to his latest 6c33c amps which you won't be surprised to hear sound very nice. The bass is really something special, powerful and controlled but doesn't overpower the rest of the music at all. Hearing them made me realise how other amp...
