For those that use 1N34A or other Ge diodes, do you just buy a bunch and test each for the ideal forward voltages? I bought a bunch from Deeco and most seem to have really high Vfs around double of the desired 0.2-0.3+ range.. Are sylvania or D9Es hard to find around here? Or are there online sources that won't charge an arm and a leg?  :-(

Try Schottky diodes? 1N5817 is a common one that should be available in Alexan or Deeco. I just measured one a while ago and got 0.23V voltage drop.

Thanks! Will do. I ordered about 20 1N34A's and spent 200+ pesos from tinkboxph, and I found out they aren't what they claim to be. 0.8 V forward voltages? I took out a magnifier and found out they are infact 5V6 Zeners... I'll probably send them an email later tonight..

1N34As should be around the size of slightly shorter 1/2 watt resistors. The ones I bought have yellow rings on the side.

That sucks man, hope you get that sorted out quick.

Anyone know where I can buy a 20k 2-gang potentiometer for a Blackstar amp? Kinda looks like this:

Hey guys, what's the best soldering iron I can get under 1.5k? Mainly for DIY pedals/mods so a 15/30 watt would be okay but I'd also like to build myself a tube amp head one day. 

Manila/Makati/Pasig/Alabang areas please!  :)

Cool! It's been a while since I last modded a Rat. Sure is fun to tinker. Try this experimental mid scoop too. SPDT or DPDT should be fine.

...and the LED/ MOSFET clipping on top near the power supply stage...

Anyone know where I can get a 3mm Bicolor LED Red/White or Red/Blue online or if possible; locally?  :)

Ordered online from Tayda Electronics for my Blackstar HT-Dist. Pin spacing was too wide for the PCB so I bridged it with wires soldered to the board instead.
lots and lots and lots and lots more to learn
