I used mouser.com for everything.<br /><br />The low filter switch popping is caused by leaking caps, most likely the two sky blue solid aluminum caps on the tone amp board, they are notorious for this. Recapping it will solve that problem.Matt's Vintage Audio Repairhttps://www.blogger.com/profile/05194860724155871918noreply@blogger.comtag:blogger.com,1999:blog-1004781035762227327.post-29815108445949020782012-07-28T13:39:34.308-04:002012-07-28T13:39:34.308-04:00Hello Matt ,

Who is your source for parts ?<br /><br />Also what do you think would cause the low filter switch to make a loud popping noise when it's pushed in . It is heard through both speakers even with the volume setting all the way down . What do you think is causing this , haven't had time to trace it myself .nonelectronhttps://www.blogger.com/profile/06713987810826623131noreply@blogger.comtag:blogger.com,1999:blog-1004781035762227327.post-28938464970573428352012-07-27T21:41:48.157-04:002012-07-27T21:41:48.157-04:00No, they were two small signal transistors on the ...No, they were two small signal transistors on the tone amp, they are 2SA725's, Q3 and 4 according to the service manual.Matt's Vintage Audio Repairhttps://www.blogger.com/profile/05194860724155871918noreply@blogger.comtag:blogger.com,1999:blog-1004781035762227327.post-75850974687591488532012-07-27T20:18:05.803-04:002012-07-27T20:18:05.803-04:00" I'm also replacing two transistors that..."
