Hey Harry,
I know that resistors aren't directional. I would check the type of resistors in the original CAT plugs, and buy the same quality. You probably need metal film resistors (1/2 -1 watt) 1% tolerance. Definitely 100 ohms and if you have enough plugs maybe a 500 and a 1000ohm resistor set. I usually buy 5-10 for each value, and measure each set with an ohm meter, -digital if you have one. Match up pairs with closest val;ues for each set. Buy them from Mouser electronics on line. They are very cheap, and shipping will be most of the cost. That's why you buy more than you need. If CAT uses Vishay resistors, I would buy that brand, but probably not.
By the way, can you solder, and do you have any silver solder? You can get silver solder from "Michael Percy" on line. Google him.
Hey Chris,
The Lyra cartridges sound a bit bright and lack bass at 47K. I hear a real improvement in freq response with lower values. My ARC ph-5 has values of 47K 1K, 500, 200, and 100 ohms. I use 100.
