solder technique, Will it hold???

[Colin Allen]

Hello @Colin Allen @EDcase.

So today I completely disassembled my ARP 9.

So looking at the internals everything looks ok.

So here are my plans after listening to your advice and tell me if this sounds like a good plan.

Plan A

So first of all I am going to buy the Perum ETU.

This hopefully will give me an upgrade then rule out if my soldering is the problem.

If it still does not work then plan B I will buy another trigger unit just in case it is worn out and causing all these problems.

Hopefully this will sort it out.

Please let me know you opinion.

Thanks

The Perun ETU++ is a definite upgrade; however, before replacing stuff it might be wise to check the continuity of the cabling and, in particular, your soldering if you have a multimeter or can get access to one.

If you're going to be doing any electrical work, a multimeter is a must.  It takes all the guesswork out of it.

I don't know if more soldering is going to eliminate any soldering problems but its good practice I guess.
