In Reply to: Loud Whistle from Amp has returned .................... posted by Cut-Throat on July 20, 2019 at 17:54:18:
After replacement of the 45 Power Tube, I fired up the Amp this morning and 'No Whistle'. Pretty sure my problem was indeed the Power Tube... Turned out to be an easy fix... Never had one make a noise like this before going bad. It will be interesting to see how it measures when the tube tester shows up at my place,

Yes, this will take some time to troubleshoot, as it is very intermittent...... - Cut-Throat 06:42:47 07/21/19 ( 0)
Did you tighten the output tube socket tangs? (n/t) - FenderLover 18:12:35 07/20/19 ( 1)
