Counter weights on your turntable...another dirty little secret?


This is more of a public awareness post for us Mid Hifi peeps who have recently made the  dive back into vinyl. I did back in 2020 and did my research and decided on a packaged deal- please be gentle on me- from one of the two biggest online sellers out there. They set up too and provided some simple instructions to finish the set up when it arrived.

Fast forward a couple year down the road and I am thinking I should bring the table to my local audio repair guy in Northern Litchfield County, CT for a check up. I was concerned that maybe something was off, and man was I  glad I did.

My turntable is ProJect Classic SB- you know that 1970's vintage looking one,  coupled with the second generation Sumiko Oyster Blue Point II. This guy is extremely  busy with endless warranty and service work- so it sat for time before he could check it out, but he knows  what he is doing. He soon discovered that the most he  could track the cartridge was at 1.47 grams-the Sumiko is supposed to track at 2 grams.

The problem was the counter weight. Next challenge was finding the right one and it was not an easy task, as tech support was tough for ProJet and he ended up fining something posted online back in 2018 on counter weights for ProJect turntables. He also reached out to a peer, who has a very  reputable brick and mortar store here in western Connecticut for assistance.

 

As many of you may know most online sellers do not even sell counter weights.

 

He eventually found what I needed- for only $35 too, but I was  shocked that this turntable was paired up with this cartridge-and this was not a cheap one either, it could not even track it properly. Why would that even happen? So for over two years I have not  gotten the  best  performance I could from this set up.

 

So as they say buyer beware and add this tale to the long list of questions when sourcing a table, verifying settings, if your new table was set up at the  factory correctly, or upgrading your cartridge

Off by about 1/2 gram. A scale could have detected this! The Shure scale is fine! Mine is still good while the cheap Ch*nese electronic scale is kaput! Turntable owners should learn to setup their own rigs! There is joy in learning!

My cheap Chinese scale is a revelation. You must have invested in the really f’n cheap one.

I agree with Jason and more.

If you can't setup your own TT you have NO business owning one.

I believe a trusted TT technician can do better than the home hobbyist. Most don’t have an oscilloscope to check output and other tracking errors. However, the OP might have noticed the counterweight was at the limit of its travel suggesting there might be a problem. 

The supplied counterweight is a standard  

"no. 183 for cartridges with weight between 7 - 14g"

The chosen cartridge weighs 6.3 gm

The online seller didn't do his homework.  It most likely wasn't  possible to get the weight any closer to the tonearm pivot.

Exactly, ghdprentice - support local dealers who are invested in customer service rather than pile 'em high, sell 'em cheap online vendors.
