Re: Remember These?

If it helps, I think I have a couple of spare PCBs for these regulators that you're welcome to. Nice and compact at 50mm x 50mm. I'm using a couple in my build, running off 7V secondaries and using the chassis to heatsink the regulator devices. https://www.diyaudio.com/forums/group-buys/254981-line...

Re: Remember These?

Not too bad, and sounds like you have a plaan. Yep, got it going again with an hour’s work swapping out the 9V heater transformer, running new heater wires to the 6H30pi sockets and the indicator light. That's a shame Steve. What DC supply arrangements are/were you using? I was using an old DIYHiFi...

Re: Remember These?

Oh pooh! Listening this afternoon and the music gently faded out. Looking at the 6H30s there were no heaters, although the blue LED was lit on the DC module. Leaving things to cool, the heaters came back, only to fade away again about 15 mins later. Looks like the regulator is going into thermal shu...

Re: What Are You Listening To Right This Minute?

Back in the late ‘80s for this one:

Not played this for years. It’s an excellent album, especially from someone so young (19) at the time she wrote the songs.
Hasn’t dated.

Re: What Are You Listening To Right This Minute?

Just catching up on last night’s prom, with Simon Rattle conducting Walton’s famous cantata, “Belshazzar’s Feast.” Not heard this until now, as I was never into the into the big choral stuff (probably due to having a crap system that couldn’t handle the forces involved) Watching the subtitles, I cam...

Re: Remember These?

Here is what I did, from earlier in the thread. I put a 2.7R 3W wirewound resistor right up against the anode tag; no ferrite. The ferrites went on behind the grid stopper as detailed below Worth a sperrymint, if only to tick that off as having been tried. Only 3 things can happen, A. nothing, B. it...

Re: Fane 12-250TC Retro Speaker.

I think doing things in front of a speaker with passive components is an under-researched area of audio, and any contribution is very worthwhile. If you think of how you might be able to kill some high frequency break-up modes around the edge of light-coned drivers, there must be ways of applying a...

Re: Fane 12-250TC Retro Speaker.

Steve, I like your approach here. Keeps the signal chain nice and simple, which is something I've struggled with when going with active EQ/crossovers etc. Chris Well, the “grille engineering” approach does seem to work a treat with this particular full range driver. For want of a better description...

Re: Fane 12-250TC Retro Speaker.

If all the above sounds like I’m saying the speakers sounded crap before I wrestled them into submission with my heroic efforts; they didn’t. There were just a couple of peaks and a bit of a rising trend that could occasionally make themselves known. Now. that the faults have been rectified the spea...

Re: Fane 12-250TC Retro Speaker.

Indeed Steve. The Pachelbel I played at Owston was a bit disappointing, being quite 'edgy'. I was talking with someone aferwards who commented that it wasn't a very good recording but the reason I wanted to play it was because experience at home is that its an excellent 'prick up your ears' recordi...

I could do that, but whether my 61 year-old ears, would hear any improvement is debatable. I’ll give it a go tomorrow.

Re: Fane 12-250TC Retro Speaker.

Here’s a bit of measurement for anyone interested: Below we have the pink noise analysis response from 12 months ago, taken sans grilles. http://i.imgur.com/f3PEdhg.jpg It’s only 3rd octave; nevertheless, the coarser resolution is sufficient to see the rising overall response, and peaks at 4K and 8K...
