Hi Toku, thank you for the guidance and input. At the time I was operating FT8 on 40m (7.074). I only realized what was happening when I heard the signal coming through my Edifier R1280t speakers in my office....a completely different room than where I was, haha. Those are always on and are used...
An old FT-1000mp that someone modified for eSSB, and being that it's pushing nearly 200w (it's a 100w transceiver)...I'm assuming some other "mods" were done, I was testing it to start aligning it...and WHAMO!....took out my DAP2002.
Well, that didn't take long at all...
I've got maybe a total of 6 hours of play out of my amp... And it's developed cracking in the right channel.
Is anyone else experiencing this issue? 3e, anything I should try?
I used the same Op-amps in mine, but then also added the capacitors that were missing in my unit. I've also got the 8Ω one and would be willing to send it in if you wanted to test that, and see if there was a difference with the caps installed.
What's the best option when it comes to installing the caps? Level 1, 2, or 3? I bought the caps for all three options just in case, but don't really feel like experimenting.
Preliminary report...(couldn't wait for the capacitors to come)
Wow, I took out the (most certainly knockoff) NE5532a's that came with the amp, swapped them out for the
LM4562NA --- Sound phenominal
OPA1612AIDR --- Same as above
ADA4627 --- Wouldn't work, realllly low and heavily distorted...
