My PQ kit 1 is done...

Posted by Vincin (A) on March 6, 2006 at 07:03:28

Hi everyone,

With help from a diy friend, we finished the built over the weekend. So after all the hard work, we turned it on and boom! one of the 47mf cap blew up, so we replaced it.

Next up is one of the resitor caught on the same board actually caught fire...I nearly shit my pants! This was replaced also and the unit seems powering up fine.

Then the hum...., we decided to re-wire the power supply board...still hum but very little and one I could live with (what to do?). Maybe because my power source is not clean, I'll borrow a power conditioner to try later this week.

Tried some test CDs, initial impression is quite good ie: extremely good bass and dynamics....

until we popped in female vocal and acoustic guitar....it really sucks ie: grainy, congested, distorted a great deal...absolutely not the way the amp is supposed to sound. I feel lost!!!

Okay...so I have sent the wiring picture to Brian for help. In the meantime, I have a couple of questions for the experts out there:

1)understand that stuff take sometimes to break in, specially the blackgates, do I hear what I heard because of this?

2)My speakers are Triangle Celius. When I tried the amp with a pair of Onkyo bookshelf speakers 86db, the sound actually seem ok, not the best sound in the world but there is little or no grain and distortion...so weird. Is there something wrong with the Triangle speakers or system synergy etc..?

By the way, would someone please show me how I can post a picture of the wiring?

Much appreciate any help with my problem.

Regards
Vi
