In Reply to: LM350 regulated DC PSU & HUM problem posted by Ewing on August 19, 2003 at 18:32:47:
Thanks a lot to you guys.I followed Groverg's advice and bought a 100 ohm 25W hum pot from tube amp shop last night. I had rewired the amp and guess what? THE HUM WAS GONE!!! Very quiet indeed!!! I can now enjoy great sweet music. Thanks again Groverg.
Jim, thanks for all your advice on LM350. I guess I'd stay with the AC in the meantime. Probably try out the regulated DC again later when I'm in an adventure mood.
PS. I lives in HK and the hum pot I bought is from Japan. The shop owener said it had very good sound and most DIYers used it. It costed HK130 each or around USD19 each. IS THERE SUCH THING CALLED GOOD SOUND HUM POT?
