Hello friends i bought Ahuja TM 50 valve mono amplifier. It sounds good. But when i connect to the phono stage it is working well. but when i connect to the aux pin the sound is feeble and when i turn the volume nob to maximum it sounds 10% only. what is the problem? I have seen 2 resistors connected across the aux port input. please any suggestions to fix. Any valve amp technicians here to help me.
