Fender Bassman

Hello everyone!

I have this 60's fender bassman 50 head. I'm doing some fixing and I found these two cables with black tape on the points. Any idea what I could do with them? Thanks

Hi Erick - The wires taped off in the photo look like an additional secondary output from the transformer to the left. Often a particular transformer is used in many products, and not all the secondary outputs are needed in every design.


What could you do with them? I would say "leave them alone".

Laney Aor series 2 100 watt

Hey there,


I'm working on a Laney Aor 100 series 2 I bought for cheap knowing there's an issue. So here it is, the amp cannot get up to loud volumes at all. Go up to maybe 1/2 volume and it refuses to get any louder but the tubes continue to get hotter and hotter. The thing is which is weird is when it's pegged at max it sometimes does this flicker to max volume very quickly and then jumps down back to the lower volume. It is red plating power tube 4. I've got no idea other than the output transformer being bad. Anyone got any experience or any ideas?

Without sufficient negative voltage, the grid will not be able to allow electrons from the cathode to the plate. I'd stick a volt meter on it to make sure you have good grid bias. (Safely!!!!)

Kurzweil K2500 renovation

I purchased this from the daughter of the original owner who passed away last year. That’s it in my profile picture and also what have to work with. It’s been standing on end in it’s road case for more than a year. The foam is completely deteriorating and I’ve got a lot of cleaning ahead of me.

Any ideas on removing deteriorating foam stuck to plastic without damaging plastic would be greatly appreciated. It’s very sticky, like a spilled soft drink. Like I said, this has been standing in this end in its road case for over a year. I don’t want to damage the plastic finish. Thanks in advance for your ideas.

Cleaning pots sustainably

Hi there,

I cleaned the pots on my Peavey VTX heritage and one of them actually ended up tearing up a gang. I have mesa boogie on the bench and I need to clean its pots but I don't want to ruin them with contact cleaner. Has anyone used Deoxit fader? I'm about to buy some.
