Last post by neiltheseal - October 31, 2025, 06:25:40 AMThe ma ratings are per output and there is nothing else plugged in at the time of the test.

Last post by neiltheseal - October 31, 2025, 03:17:28 AMIt is weird
Here is a video link. The 3 jacks on the right are all 500ma. They don't seem to register the input and the led doesn't turn on. These jacks work fine for other pedals as you can see.
The 7 jacks to the left are all 300ma all work fine on the Archibald.

Last post by madbean - October 31, 2025, 12:43:13 AMAre the mA ratings per output or are they shared amongst them and do you have anything else plugged in simultaneously? There should be no operational difference between a 300 or 500mA output so this is curious.

Yeah, you could try replacing Q2 and Q3.

Tech Help - Projects Page / Archibald only works on 300ma ...
Last post by neiltheseal - October 30, 2025, 11:35:21 AMHello
As the title says, my Archibald only works on 300ma power supply, not 500ma. Does anyone know why this might be?
I have been troubleshooting this thing for a while as it intermittently works and doesn't work. Today I finally figured it out. I have a power board that has 7 jacks @ 300MA and 2 @ 500ma. It works depending on which I use.
At 9v the 300ma dc input jack measures 9v as it should. However the 500ma measures about 2.4v.
The build doc says it should work on 500MA (and should work better) so i'ma bitconfused. Plus itused to work in the 500ma jacks as these also goto 12v.
Does anyone have an idea why this might be?

Last post by Kardnez - October 30, 2025, 11:14:50 AMHello,
originally, Q2-Q13 were 2N5088 and Q1 was 2N5089. The LFO wasn't working, so I found a suggestion in older posts here on the forum to replace Q11 and Q12 with 2N3904s. This did the trick; the LFO now works. Since the input signal only goes as far as the base of Q1 and then stops, I also replaced Q1 with a 2N3904. Unfortunately, without success. I removed Q2 and tested it with a transistor tester; according to the tester, it's OK. I reinstalled it. I haven't replaced Q3 yet.
Could it be possible that several 2N5088s are faulty?
I can try replacing Q2 and Q3 with 2N3904s.

Last post by NorthCoast - October 29, 2025, 05:48:50 PMHi Holger,
You mentioned you've replaced 3 transistors, what transistors did you have in there before?
Is it possible Q2 and Q3 need to be replaced?
It seems like every time you replace a transistor, there is an improvement.
