Resistor in phono stage

Ok,thanks for that.

Im using the H weight on the arm.Im thinking it could be a combination of several things,not necessarily the resistors.Ive used a spin cleaner on my records for the first time,and that has changed what im hearing too,for the better,room acoustics,hifi rack,speakers,powercords, interconnects,etc..I will give the supex more time to settle in.Not a bad little cartridge,i must say.Using the a supex step up transformer of course.cheers.

Using the a supex step up transformer of course.

Ah! Which of course explains how the 54 db gain of the phono stage suffices for use with a 0.2 mv cartridge.

But it also adds to the possibility that either resistors or capacitors a previous user might have installed in the phono stage could be an issue. For example, suppose a previous user had installed 1K resistors, for use with a cartridge having a rated output in the upper part of the LOMC range. And let’s assume that your SUT provides a gain of 10:1. That would mean your cartridge would be seeing a load of only 10 ohms, which stands a very good chance of being low enough to result in the adverse effects Lew referred to in his previous post that can occur when load resistance becomes excessively low.

From the perspective of the cartridge, use of a SUT also greatly increases the effects of any capacitors that might have been installed on the loading terminals within the phono stage. Which as I mentioned earlier could conceivably have been done to conform to the loading requirements of some moving magnet cartridges.

So I would definitely open up the unit and take a look at what if anything has been installed on those terminals.

With SUTs, it is the loading of the transformer to prevent ringing and also to allow it to express its turns ratio that is important.

If loaded with a value too low, the highs will be rolled off. If loaded with too high a value, there will be ringing, which is say distortion, most audible as being bright and in your face.

Low output cartridges by themselves are insensitive to loading. Its the SUT and and also the preamp where the loading becomes critical.

Awesome guys.You probably helped alot of us out.thanks
