Quote from: pasha811 on May 03, 2022, 09:40:56 AMIf GK2A is not switching type why it is soldered with three soldering joints to the PCB?
Quote from: philjynx on May 03, 2022, 09:47:53 AMIt's just mechanical attachment... Think glue. Many PCB mounted components have extra solder points to physically attach them and also to help avoid pulling tracks off the PCB if they are subjected to external forces (like us tripping over the cable plugged into them).
Quote from: pasha811 on May 03, 2022, 09:40:56 AMThanks Admin!If GK2A is not switching type why it is soldered with three soldering joints to the PCB? Is the third one an additional shield of some kind? Shouln't it be 2 conductors (signal and ground)?In the meantime I have asked Roland Italy through their #1 Reseller if they have a spare part... not many chances but I found a GK2A wart body plate in 2016... CheersPaolo

Quote from: pasha811 on May 04, 2022, 06:39:53 AMRoland has 1 spare but only the board with components. The GK2A connector needs to be moved from old to new board. 50 Euros. That's good news but...Today I tried with a pin made as a hook to restore the springiness of the female Jack retention mechanism and I have found out that the casing third leg was not firm into the hole in the PCB so I resolder it.Unbelieveable... now it seems to work. I played several chords and then rock the guitar and instead of the usual stutter I got continuos sound.That's good news but I think I will order the PCB anyway just in case, what do you think?
Quote from: gumtown on May 04, 2022, 12:57:33 PMUnless the GK-2A is of special need to you, I would go buy a new GK-3 and be done with it.If you were to to put hourly rate on your time for trying to repair something, the cost adds up quickly if you are inevitably fighting a losing battle. That is my 2 cents worth of 'words of wisdom' as time goes by, time becomes more valuable.or maybe I'm now less tolerant to broken things.
