Hello Everyone,
I am just venturing into the audio DIY world, looks like its an amazing ride.
Seems I have hit my first issue already - cant seem to get my preamp and amp to work from the same power source.
Preamp - XH-A901 - NE5532 (with a rectifier at power supply) - https://www.amazon.in/InkOcean-XH-A...hild=1&keywords=ne5532&qid=1628521380&sr=8-16
Amplifier - XH-M510 - TDA7498 - https://www.amazon.in/Triupy-XH-M510-TDA7498-Digital-Amplifier/dp/B07RCHC6ZL
SMPS - LRS-200-24 - https://www.amazon.in/Meanwell-Switching-Supply-LRS-200-24-Transformer/dp/B00YMA7I7C
Setup - audio source > XH-A901 > XH-M510 > Speakers
The setup works only if the preamp is powered separately, with another SMPS.
Tried bypassing the rectifier on preamp, since it was receiving DC already, but no luck.
Should I have a common ground for both boards or something on those lines?
Pretty sure I might have got something basic wrong in here, hope you guys can point me at the right fix?
Thanks in advance!
Also happen to have a 6J1 tube preamp (AC 12v) https://www.amazon.in/preamp-amplifier-Pre-amp-Headphone-buffer/dp/B06X9T3SRS, was planning to put this in to the above setup as an optional preamp - like switch between the 6J1 and NE5532 preamp with a rotary selector.
