2 Unrelated questions -buffers and transformer mounting

[Peter Daniel]

The blue pot is Panasonic. I have 3 of them: 10K, 50K and 100k.

After reading all the raving about their sound, I was actually a bit disappointed after listening. The sound seems to be rather soft and a bit veiled. It may appeal to tube guys, but I prefer more air in the presentation. I also compared them to my fixed series Vishay, switched shunt Holco attenuator, and I didn't have any doubts which one wass better.

However the pot seems to be very well made and the the feeling of the shaft (when rotating) is better than anything I tried so far. Matching is wild card: 10K seems to be accurate within 0.2dB between channels, 50k is more like 1.5dB.

I would advice strongly against using zip ties, as a transformer can become very hot (100c+). This is especially true for big trafos under heavy load.

In that situation, you will have wire insulation melting as well, as it's usually rated 105 degC. And this is much bigger problem

Thanks Peter.

It doesn't sound like s-c pot I am using. It is s-c but not Panasonic. It's made in Taiwan and come in 10K and 50K (I use) Log. The channel balance of the ones I've tested, none have been worse than 0.5dB and typically 0.3dB.

Maybe I should get somebody to try one of mine... ? Carlos, do you have PayPal?

No.
Visa card.
Bank transfer, etc.
To send it from Australia will be expensive, no?

Can you post a pic of your pot and tell us what's written in there?

Thel have a minimum order charge of 50 Euros.

I was also going to ask you to put up a picture Joe. I am sure somebody would recognise it and find out the source!

And as Carlos asked, how much is the shipping from Oz? And would it be cheaper to send more than one at a time (I do have Paypal).

Joe,

I'd be interested to try one. Paypal is fine?

Cheers,

I have just read in another thread that Newark, who are owned by Farnell, provide information on the speaker drivers they sell. The same drivers sold by Farnell subsidiary, CPC, have no such information.

Good service seems to be a way of life in the USA whereas over here, the customer (at least the small one) is seen as a grovelling nuisance who doesn't deserve the time of day!
