Re: Disappointing Audiolab

Hi Richard,

Well, the Wimas are just standard commercial grade caps. It is not that I think they must be terrible, it is more that I'm pretty sure that there is room for improvement. More...

Re: Disappointing Audiolab

Well,

8 months on and I opened the case again. I ended up changing about half the caps before, leaving a lot of the small (mostly 100u 25v) ones as there was no sign of them leaking/bulging at the...

Re: huanshop2015

Hello Stuart,

Oh well, at least you finally have your caps.
You never know, the "spares" might come in for something.

Regards, Phil.

Re: huanshop2015

They sell crap product but have good feedback. Surely that is totally corrupting the whole point of the feedback system.
Unless they "allow" you to say the goods were crap BUT they were good to...

Re: Simple Mains Filter and Spike Suppressor

Hello Phil,

It should help with both but don't expect it to be cast iron a cure all. Depending on the nature of the cause they can be helpful but for airborne RF the valves and all components can...

Re: WD88VA didn't survive move

Why not just get a pack off ebay?
Probably quicker.

Re: recapping speakers

I have no personal experience but I noticed a while back that Mundorf do bipolar electrolytics for crossovers, 2 types I think. If you wanted to stay with electrolytics they might be worth a look.

Re: recapping speakers

Hello Stuart.

Bipolar electrolytic caps sound poor anywhere in crossovers in my opinion. Obviously a 60uF film cap would be huge, I would go with a new 47uF 'lytic and then make up the difference...

Re: KT5881 valve change

Hello Gary,
May I ask why you thought the KT66s would be a suitable replacement, were you told this by someone?

John/anyone,
Recently I joined and then left a valve and valve amp group on...

Re: Kt5881 bias

Hello Gary,

Different valves, and all components come to that, make a difference. Sometimes very subtle, sometimes more obvious. If you prefer the Sovtek then they are better for you. I have...

Re: Cv181

Hello acorn,

You are advertising somewhat "specialist" valves and I believe that the WD forum is fairly quiet these days. Are you offering these valves anywhere else?
I think you would probably...

Re: KT88s

It depends BOB,

Are they the current production Svetlana or the old "original" St. Petersburg winged C ?
If they are winged C then I would do a bit of research as these are becoming quite sort...

Re: Fixing tear in HDA driver

Hi Adrian,

I have not personally handled a HDA driver but I would suggest a glue that to some degree matches the characteristics of the cone material, ie paper for a paper driver. If the cone is...

WD phono load

Hello all,

Regarding passive pre's etc, could someone tell me the minimum load for the WD phono?
I'm not concerned for myself, my home made one is shunted 47K which I'm sure is fine. It would all...

Re: Screened lead

Hello Greg,

The silver wire I used was from HiFi Collective. It is HGC branded in their "hook up wire" section. I used 0.5mm as it is only for signal use. I expect the same stuff or similar is...

Re: Screened lead

Hello all,

Should anyone be interested, I now have fitted in my Phono (from PCB to o/p sockets) solid silver single core in PTFE sleeving. No hum issues.

In my KaT88, as these amps are known...

Ah, Richard beat me to it but I agree.

By all means speak to IPL but unless you listen at nightclub volume I'm sure the combination will be fine. Don't complicate the issue by changing 2 things at...

Re: Pre II cathode follower query

Hi Adriana,

Not sure what you mean by "cap discharge noise" but if the noise is louder than the music then I really don't think that it is a failing capacitor. That will typically give a sound...

Re: Pre II cathode follower query

Hi Adrian,

I would have thought that it would be perfectly safe to take the cap out of circuit but leave the resistor on the offending channel. See if that seems to cure the problem. Then you know...
