still looking for tips for my ungar hotvac model 4000
I'd rather buy some new tips then shell out for a den-on sc-7000z or hakko 808
so please if you know a place with tips let me know please!!
I'm looking for tips for my Ungar Hotvac Model:4000
this rude boy right here

I have to tips but I'd like backups / more sizes. I found one place
action-electronics.com but they have NLA (no longer available) :(
I numbered my questions 1-4
I'm looking to purchase parts for my tr 808 but I'm some what confused. I want to start by recapping, replacing diodes, replace switches for the 16 steps, and then re-calibrate it.
The problem is that I'm not 100% sure what kind of diodes to purchase. I have...
I am plowing through this teach yourself electronics book & anytime I have to calculate anything to do with voltage it is always voltage drop.
Why don't I ever have to calculate how much voltage is left after the drop?
I asked a friend this and he said there "is no voltage left over"...
Thanks to both of you two. Both of the explanations really help.
One follow up question. In a reverse biased diode, where does the energy go?
Does the energy get from stopping the current get turned into heat and absorbed by the air like with a resistor?
I have an understanding problem with diodes, and current.
I understand that silicon diodes are doped to give part of them P & N.
The P sections having more holes, and being called an anode.
The N sections having more electrons and being called a cathode.
I understand that diodes are not...
dknguyen; I see now that it is clear that these Voltage measurements i.e V out is referenced to ground and being measured across the resistor, Z2, that makes a lot of sense now. I wasn't aware that if Vout just has a name w/o anything else by default it is referenced to ground...
I am still a little bit confused. after crunching some numbers from doing calculations with resistors of different values.
Say the two resistors are of different values.
V = 5 , I = 5/6 , R 1 = 1 , R 2 = 5
If I where to measure the Voltage drop across R1 I would get V 1 = 5/6...
I have some questions about the voltage divider.
Voltage divider - Wikipedia, the free encyclopedia
Here is what I think is going on.
The voltage starts at the negative terminal i.e V in then goes to the first resistor Z1. & in my mind i'm thinking why isn't Vout determined by current...
