更換SME 3012R 唱臂軸承
SME 3012R 唱臂原有的軸承是尼龍造的,很多用家都會把它換成金屬軸承以達到更好的音效。我在ebay上發現有人提供用CNC方法製造的青銅合金(95% Copper, 4% Tin, 1% 14K Gold)軸承,便打算買來試試。

Power supply for Garrard 401 - update

After listening music for 2 hours, the voltage became not stable. I found that the power supply was hot (due to LM3886) and it affected the function of L1 lamp in stabilizing the oscillation. Therefore, I changed this part to diode so that it is not temperature dependent.
