Some personal notes to build the Befaco Percall.
Its a euro module.
I purchased a complete kit. Has all the parts and a printed BOM, instructions, etc
looks great. Everything is through hole.
ic Headers first
100K rEsistors next
They are small 1/8 watt
Diodes next
Capacitors -- 104 - 100nF
There are 24 of these
101 - 100pF
Transistors
iNsert ICs
I made the mistake of placing some of the headers that join the two boards on the wrong side of the PCB.
Ed of Elk Elektroniks helped me correct this error.
Put the jacks on the top PCB but only solder when the panel is firmly on.
tHIS is what the rear of the module looks like.
All the components should face one another. It's a tight squeeze.

ReplyDeleteHi JonDent!
ReplyDeleteI am putting together a DIY BEFACO PERCALL too, I only have a question in the welding of some resistors
It is just to know if the resistors R68 and R72, R69 and R73, R70 and R74, R71 and R75 have to be separated or not
When soldering the resistors, they join together because they are very close, must they be separated or is it okay for them to join?
Does your module works well, does that union of resistors generate problems for you?
I see on your post (photo: THE HEADERS ON THE LEFT PCB ARE ON THE WRONG SIDE) that those resistors are firme joined together, you can see them at the bottom of the pcb close to the CE legend and the trash can logo
Hello Ric,
DeleteThe module works well.So I think there is a connection.
Though I don't have schematics so can't be totally sure.
If i ever have this concern I usually desolder, then check the PCB under magnification before re-soldering very carefully. I hope this helps
thanks a lot!
