Re: Phono II advice Please!

Lyndon,

If i understand your drawing, you wont be able to reduce the volume to zero.

Re: Phono II advice Please!

That should be fine. It was just a thought that if it was very low in value it might have been loading the o/p of the Phono too much and effecting performance.

Re: Mundorf Mlytic HV caps

Hi Greg,

You are right, I did not build my Phono from the kit so it has some differences, especially the PSU. I've had a look and I don't seem to have a copy of the series 3 circuit, perhaps if...

Re: KEL84 Conundrum/advice

Hi Richard,

So are you saying the sound has changed or that you have started to notice something that was there all along?

If something has changed, then obviously you should be able to get it...

Hi Intenso,

Yes, good aren't they! I was quite taken aback after fitting them in my power amp.

As to Phono, the "quality" of the change was similar but quantity of improvement was a little...

Re: WAD 300b hum and buzz

Hi Adrian,

I would tend to agree with Chris, most likely you have damaged a connection or component when you were poking about. Open it up again and have a good look around for a broken wire or...

Re: Well I simply can't believe this....!

Hi Neil,

Although I have not used them in the same positions, (so I could be wrong) having fitted a few of both, my impression is that the Mundorfs sound better the the "standard" Audionote ones....

Re: Well I simply can't believe this....!

Hello Neil,

I recently changed the PSU electrolytics in my Kat88 (Mundorfs) and found this to be very worthwhile. Mine were about 20 years old.

Re: KT88 choice

Hello Tony,

Thanks for that info. I am still happily using the JJs for now but trying something different is always a temptation. I will view the TADs with caution.

Re: CF - mounting by-pass switch

Hello Graham,

I've not thought it through fully but you might be able to fit a double pole changeover relay at the input, that bypasses the active stage. If this was powered by the heaters,...

Hello Mark.
The heaters are raised to protect the CF valve. Measure on the 2 heater wires, not to 0V, although it looks close (7 volt difference)

If you have not experienced any problems with a load as low as 10k, perhaps a low load, though not ideal from an electrical point of view, in the real world is not all that significant.
