Tim Posted October 2, 2014 Share Posted October 2, 2014 So I'm walking the dog last week on trash night. I notice someone had put out a small amp. I walked over and took a look (thinking it was a little solid state piece of crap). It was a Kalamazoo Model 1 tube amp in remarkably mint condition. So, I grabbed it and replaced the tubes (one was shot). It powers up, but with a serious hum. Not sure what to replace next, transformer, caps...any thoughts? Would love to get this thing working as research has indicated it actually has tasty tone potential. Link to comment Share on other sites More sharing options...
davesultra Posted October 2, 2014 Share Posted October 2, 2014 I would look at the filter caps next. How come I never find any cool stuff on trash night? Link to comment Share on other sites More sharing options...
Gitfiddler Posted October 2, 2014 Share Posted October 2, 2014 There was an old harmonica player seen driving around your neighborhood looking for his old amp. Just kidding! Those old Kalamazoo amps can get cool tones. Good luck with it. Link to comment Share on other sites More sharing options...
barrymclark Posted October 3, 2014 Share Posted October 3, 2014 Now THAT is cool! They are definitely a hit with the harmonica players. Link to comment Share on other sites More sharing options...
Genericmusic Posted October 3, 2014 Share Posted October 3, 2014 IT definitely would be a hit for me. I've been looking for one to go with my KG-2. Nice find. Link to comment Share on other sites More sharing options...
DetroitBlues Posted October 6, 2014 Share Posted October 6, 2014 Filter caps are the first thing I'd have checked besided the other tubes. Link to comment Share on other sites More sharing options...
slider313 Posted October 9, 2014 Share Posted October 9, 2014 New power supply filters and a new bias cap are a must. That should cure the hum. I would double check all the grounds and make sure to install a three prong power cord. Link to comment Share on other sites More sharing options...
Tim Posted October 9, 2014 Author Share Posted October 9, 2014 Thanks everyone! It's all on my list (including learning the harmonica:) Link to comment Share on other sites More sharing options...
