Re: The Other 13E1 SE-OTL

Two thoughts - 1. If the valves are that precious, maybe some sort of soft start up, a series resistor will probably be enough. 2. Common mode rejection choke type filter where it goes into the amp, lots of suitable CM ferrite chokes and caps on RS site. Google for info about CMR filters.

Re: Snail Phono Pre

I'm pretty sure I copied the output cap/resistor detail from the WAD Phono 2/3 design where they used an ecc83 as a cathode follower. OK, so just on the basis the designer can't know what's going to happen to the amp in service, so any kind of screened lead, short-circuit accidents, who knows. So l...

Re: Snail Phono Pre

Good lord this goes back a while. :D 3. What is the 1k phono series output resistor doing? I see this is the same arrangement as the WAD Phono but wondering can I remove and what is the risk? Not sure in this case, but in the transistor/op-amp world, it may be provided as some sort of short-circuit ...

Re: Room Treatment (Split from Owston thread)

Ed, I didn't read it like that at all. I read it as, just an explanation for anyone jumping into the thread with no clear idea what it's all about. :D

Info only. :D

Re: GK-71 - economical build.

If only for triode mode, has anyone tried tying the screen grid to the signal grid?

Re: Nothing In Particular

Try quotes for fully comp. I've actually found those to be cheaper than just 3rd party. There's probably some twisted logic behind it, but I can't fathom that. Chris I know the answer. Used to use TPFT a long time (old motorbikes), went to renew at some time latterly, seemed even more expensive, th...

I would say, no. :D

That's what I was thinking of.

Re: Owston 2019 - Listening Impressions

As sublime as Thomas’ OB’s sounded, (And they did - highlight of the weekend for me) those phase plugs did make me think of the Korova Milk Bar... Seems a good spot to say thanks guys, had a great weekend and there wasn’t one single system played that made me think of the kit and forget the music. ...
