last christmas I bought a secondhand laptop to do some recording away from the studio, the bella tapes. It occurred to me that I might resurrect the amp testing stuff using this laptop. I was intending to do the testing on the mofo, which I have decided to finish, despite the setbacks. So I used the...

biblical rain here...

in the last 30 mins we've had 15mm..at one point for 5 minutes it was coming at 38mm per hour.

and here is the original mofo...
I seem to have lost the plot

mmmm...

last installment, I hope...

Just checking Ed when you say film stencil do you mean the cut sheet for applying paste or the solder resist mask on a PCB. I find having a metal paste stencil makes life many many times simpler when using a hot air gun. I would imagine using one and a oven would almost become trivial. yes, the cut...

thanks guys I think I'll stick to through hole if I ever do another amp. The method Ray outlined with the rework is the method I used but to make it work I reckoned I needed film stencils to avoid bridges. Nick did my first breakout for me and I had to remove a couple of bridges with wick, it was at...

I'm still a bit shy of smd...I've only used my rework station once and lost interest when I found it impossible to find acetate masks. I gather the situation has changed somewhat in regard to masks...but nevertheless, even tho I bought the usb microscope the deteriation in my eyes is not helping.......

what a difference a few hours can make.... when I read Ray's post and link the talk was all about heavy handed police behaviour ....then the news at lunch time focusses on the fact that the demonstrators were using rape alarms to make as much noise as possible... well, in view of the fact that this ...

gonna have to watch it now. I haven't watched it since the original beeb series. somebody bought me the dvd and it's still unopened in it's original cellophane. It was the first time I'd seen Neve McIntosh and I immediately fell in love. I'm not disillusioned by her portrayal of the lizard women in ...

post deleted...I now understand the previous post...

t means transistor!

shame on you....snigger

thanks Mike it does help... although, after reading all the TI ap notes I still don't understand why I need drive current to overcome the GS charging capacitance at low frequencies like audio. I am content with my lack of understanding though. I've amended the diagram to take R4 down to 68R and R3 d...

This is why I mostly use plain matrix board – stripboard if I must, but that can be a bit of a pain, cutting all those tracks, then cocking it up by cutting in the wrong place.... or missing one out... yeah but no but.... I thought I was being modern by giving up the paxolin and matrix board and tw...
