You can also try opa1642 with SMD to DIP adapter. Regards Sachin

Never faced any hiss issue with this. I have built some of them in plastics and even in wooden enclosures, all were dead silent no hum or hiss. Try changing to another opamps if that solves the issue. Regards Sachin

Hi CNC phonostage PCB dimensions 107 mm* 76 mm Power supply 100 mm* 63 mm Regards Sachin

Another one built Regards Sachin

This time a bad RCA cable. I have changed the cable and it’s started working again. However I messed up with headshell, the plastic slider where cart screws are mounted is broken. I tried to glue it but tits not sliding anymore with headshell screw turning freely. Does anyone know the source...

I have cleaned all the contacts with IPA and later with pencil eraser. The new cart is Technics EPC 207C. it was good for a day as I listened it with 4-5 albums that day. I started it again today, but it was all buzz/hum in left channel and sound only in Right channel. I did not get time to...

Dear team I am having issues again ,left channel again out. I can hear the buzz in left channel as like earlier problem. I am afraid that my TT is ruining my carts. Is this even possible? Regards Sachin

Hi Guys thanks for your help. It turned out to be a bad cartridge. I was bought used in mint condition. I mounted it first time while checking this TT. I have changed the cart and it started working fine. Regards Sachin

Hi Did swap the RCAs and they are fine. The left channel from TT side is having issue. Preamp is ok too. I have again checked the continuity (beep on DMM) from TT RCAs to RCA cable. The left channel ground from TT side showing continuity with right channel RCA cable, but no continuity between TT...

I did check the continuity from headshell to RCA and it's fine. Regards Sachin

Hi I am having a left channel drop issue with my Elac 750 II. I did all the basic checks like continuty, cart, headshell connectors cleaning etc, but issue still persists. I have read here that issue could be with muting switch. I have cleaned them with IPA and pencil eraser. They look Ok to me...

You can mount them on panel. Regards Sachin

You may try swapping Opamps. I would suggest in same types of pairs. There are some members posted their experience about mix n match opamps, but they always returned to having same opamps in both stages. For start, you can try NE5532 in both the stages as you already have them. Regards Sachin

Hi Mark Please Measure the voltage on big power resistors wrt central ground. if input is okay and same on -ve and +ve rail then we have to check soldering of all pins of preset in that line. Regards Sachin

Hi Mark I suggest you to check solder joints. there could be some dry solder on one of the cap or diode. Please re do all the joins with hot solder gun. This type of issue never happened before. Regards Sachin
