69 Fender deluxe,Problem

Your amp has 2 tropical fish Mullard caps in it, easily identified. They are rated at 400VDC and take quite a beating over the years. Milkman makes this point (somewhat indirectly), check those out first.

The other thing to note is that Fender in this year used some resistors that have been refered to as the 'Jamaican resistors' and are not of the quality that proceeded them. A great check for this, and this would be a separation of the resistor lead to the body of the resistor AT THE RESISTOR, or even a cracked resistor, is to pull the chassis and chopstick it out in a dark room. The cracks or lead separations will spark a bit.

'Jamaican resistors'

Jamaican resistors? Red Gold and Green only? Sounds like Jamaican vinyl - snap crackle pop. I once had a Jamaican pressing with a bug pressed into it!

[rooster]

Haha! The Jamaican resistors are somewhat glossy looking, BTW. On the amps where the fishpaper would warp like a rollercoaster, sometimes the warping will put stress on a particular resistor. The dark room is a good method.

Thanx Guys,Ill try the dark room chopsticking the resisters,I replaced a bunch and that method sounds encouraging.I be back and will report my progress.Mikey

[Firestorm]

Does it have any film resistors in it (in high voltage positions)? The film is spiral cut and sometimes when stressed will burn open and then arc. Mostly this opens the coating so you can see. Sometimes not.

After getting educated about flux and some problems associated with it.

I usually will clean the board after soldering with denatured alcohol, which dissolves it.

Then I moved on to using what's called 'No Clean flux' eutectic solder.

It is 63/37 solder with a single melting temperature and it sets up hard without that 'cold joint', plastic stage that can happen with 60/40 solder.
So a higher Tin content.
