Cartridge set up questions - Spacedeck / Space arm

I have recently obtain a used Spacedeck and Space arm setup. They are the older version. The space arm is the carbon fiber version which is a version older than the latest Ace Space arm.

I have encoutered two problems during set up.

1) The cartridge is too light or the counter weight is too heavy. With the cart installed at end of the head shell, the VTF is fail to meet the required VTF of 1.5 to 1.9 gram.

I had to put a small piece of blu tak on the headshell to provide the correct VTF. Is this normal or did i do something wrong?

2)The left channel is about 3 db louder when playing pink noise. The balance is perfect when playing cd. Again, did I do something wrong?

Please help.

I doubt that the cartridge is set to its null points as you've described above. I understand what it is you are trying to do however. There are accessory weights usually available that mount between the headshell and cartridge to solve the balancing problem. You might want to disclose the cartridge you are using and perhaps the community will respond with a vendor for the weight. Then, use the proper setup tools to install the cartridge for correct overhang, etc. Good luck.
