Re: mass loading speakers

Can you take a pic of the capacitors ? Electro's are usually cylinder shaped with flat tops and bottoms. They will probably have a u or uf value printed on them. Film caps are usually oblong or square shaped. Don't pay to have it done. I will help through the forum if you want. Sony cdp-s1 is going ...

Re: mass loading speakers

If they are electrolytics, just replace the capacitors in the xover. If they are film caps don't bother. They should have markings to tell you what value they are. Resistors and inductors don't degrade. Job done apart from checking all the solder joints :dance:

Seriously, if Mr Brook buys NVA then i am done with it. The MCRU business model could not be further away from Richard's.

Re: The BMU Bandits

I stopped using mine a little while ago. Couldn't hear any difference when i removed it. May put it back in and see if i detect anything.

Might give them a go. Certainly a lot easier on the wallet than the charcroft bulk foils that i was also thinking of. :dance:

Nice explanation there Stu.

Would that 10k be the shunt resistor?

Cheers.

Best wishes.
Alfi.
The resistor in series with the signal (10k) is called the "series resistor". The resistor to 0V is called the "shunt resistor".

Re: P50 Stepped attenuators

Deos a stepped attenuator have a single ohmic value. Wouldn't it change as you stepped the volume from resistor to resistor. Yes. I think 10k would be the least resistance or the volume would be at max all the time. The resistor in series with the signal is the value given for the attenuator (10k, ...
