doe maar wel voorzichtig dan, zitten al genoeg gaten in het paneel. ;Ddetonator said:Zodra je hem kompleet af hebt, maak ik een gaatje.dagoose said:@detonator: thanks! je bent altijd welkom om een keer te komen checken als je in de buurt bent hoor.
BC182L differ in pinout, compared to BC182B.dagoose said:Ok.. strange.. i had some bc182L's in there and a couple of BC182B and the L version didn't work and the B version is working.
In some kind of way the collector of the L had 7v and didn't go to 0 while the B had 12v and went to 0.

this would be much more usable in mastering.

hmm i still count 6 frequencies?
Depends on your definition of 'the rotary switches' for frequency, Q or boost/cut, which original resistors you are refering to and how your switched pots substitutes connect to pcb.prescott said:In the excell sheet there is a lot a description about changing resistors/sorting out if using stepped switches.
Is it possible that my unit is doing crazy thinks just because a have the rotary switches with the original resistor values on the pcbs?
Jeffrey will know better, but FI the law bending 1K5 resistors (R114,115,111,112,...) at the CCW end of the frequency pots will then be one side connected, doing nothing, when the pots get substituted with the switched string of series resistors. The calc sheet is based on listed values in the calc sheet, so if you FI keep the series resistors (R87,61,83,58,..., these are in parallel to prementioned law benders, connecting to virtual ground and 0V reference voltage, and already part of the series string at the switches), the filters center frequency will be different (FI the previous 2kHz-20kHz range would respond for a 1.528kHz-4.896kHz range instead when you keep the 3K6 resistors R61 and R87 instead of using 0Rs/shorts).I've seen Dagoose's unit (pics), and he also have those resistors in their place...
Do whatever matches your plan best. This is DIY. There is no hidden formula in the calc sheet, so feel free to come up with different parts values.Should I change the values/sorting out as written in the excell sheet?
read the 'readme.pdf', partly quoted by dagoose some posts above.And where can I find the description about the calibrating?
At least different.prescott said:I've built my unit using the ring resistor list from the sheet, and with the original cap and res values marked on the pcb.
Now it doesnt work fine.
probably 2n2 for c85,c63 instead of 6n8 and series resistors 3k6 for R87,R61 fitted as well, switched resistor strings connecting to the center and right hole of the pot outline, left side hole of pot outline unconnected, resulting in a frequency range of 4.725kHz...15.135kHz. A little different from 2kHz...20kHz, but should work.If i change the values on the pcb to values in the sheet will resolve my problem?
example: I have all the ring resistor values from the sheet but i have 2n2 for c84,c61 instead of 6n8...
