Today I got a hair cut and shaved so I am significantly less hairy than I started the day. I also got my fruit sherberts which I was rudely denied last weekend.
All in all, it was a decent day. I also had a look around while I was in town then bought a few things here and there.
But that's not what was the major part of the day. What happened that I felt was really important was that my tubes arrived for my amp. I got them, opened them up, and set about trying to install them into my amplifier.
Well, I first had to figure out what orientation they needed to be installed in, luckily there was a guide notch on them, so it's hard to put them in the wrong way, so I used that to correctly orient them, and in the went. Then, I detached the amplifier from the cabinet and and crudely sat it atop the box with a few extra wooden struts I'd pulled out. I connected up the speaker, then put some rubber gloves on, and connected the power and a guitar.
I powered on the amplifier, and unfurled the multimeter. I set the multimeter up across the point that I had spotted earlier in the week, that was noted on the instructions, and got a reading. I was looking for 11.5v, but saw that it was at about 11.2 after it seemed to have finished warming up. I located the bias potentiometer, and gave it a little turn, and found a reading of 11.7v, a little too high, based on what I'd read, so I had another little adjust. Spot on, 11.5v. I was happy with that, so I turned the amp off. Disconnected the multimeter, turned that off, disconnected the power, then the speaker, then reattached the amplifier to the cabinet, then the speaker to the amplifier and the power to the amplifier.
I turned it all back on, connected up my guitar, and there was noise. Not extra noise. The noise that was supposed to be there. The noises I've been waiting to hear. I played for a couple of minutes to make sure that the problem (extra noise) was banished, and so far, the problem has not resurfaced, and I played for couple of hours, I've definitely had the amp on for about 5 hours.
All in all, I feel like I've learned something, and now I have a working amplifier again. And oh does it sound good. I don't know if it sounded this good before, but I definitely like what I'm hearing now.
Have an excellent day! You're all my favourites!
