Just a suggestion to everyone, rather than recreate all the interesting debate but also noise and nonsense, just read the DIY Audio thread.

Hello to all interested. Now the 7-th and 8-th versions of this device are available for MM and MC cartridges respectively. They are distinguished by optimal wiring and have protection from statics

But most MM cartridges WANT and are made for 47k, not 150k….

You can parallel something like 70K over the 150K SMD and get 47.7K. Perhaps that 150K resistor could come unsoldered

Now I can offer you a new version of the factory-made board, with gold-plated contacts at a cheaper price, including a power supply of your choice - either with a step-down transformer and stabilizer, or a DC-DC converter, operating from any unipolar voltage source from 4 to 30 Volts.
