    PPA v2 construction discussion

    Quote: Hi again,   I finally found out the source of my problem, it turned out that I pulled too much current from the PSU (DACT CT-102). The power supply is rated at max +/- 200 mA, but when I measured the current going through my PPA V2 using my bench PSU I only measured 150 mA when...

    Well, they didn't get hot, just sligthly warm.

    OK, so I have a problem. I turned on the amp today, and I measured 15 V at the left- and ground channel, luckily I didn't plug my headphones in. I suspected that the Q3's were fried, and so it turned out. I simply replaced them and everything was ok. I measured under 10 mV at each channel.  ...

    My PPA V2    Here are the pictures:     I have more pictures of my PPA V2 on Photobucket, just follow this link: http://s789.photobucket.com/albums/yy179/vgjako/PPA%20V2/   I have only used high-end components on this amp, listed below is the parts used: - DACT CT-102 Audio...

    I just finished building this amp yesterday, and I knew from various reviews that the amp would be good, but not this GOOD!   Listening Impressions: The first thing I noticed was the separation of the instruments, I was listening to Telegraph Road by Dire Straits and heard many “new”...

    I managed to find both transistors on ebay, so now I am almost ready to start assembling my PPA V2.

    PPA v2 construction discussion

    I have trouble sourcing parts, so I was wondering if anyone had some PN4392's laying around, I will need at least nine of them, more would be better. I also need the output transistors, MJE243 and MJE253, I need at least 3 of each. I can pay via PayPal.

    PPA v2 construction discussion

    Hi,   I have drawn a schematic which shows how I think it should be done:     As you can see, I am running the ground lead to the ground plane. I am measuring 30 V from + to ground, everything seams to be working well. Wouldn't this configuration be correct, isn't this what you...

    PPA v2 construction discussion

    One last question: Am I supposed to leave the TLE positions open or jumper them? I would guess I should leave them open, because if I jumper them it would mean that VH+ and VH- will be connected to ground, am I correct?

    Ok, I get you. Thanks for taking the time to explain it to me.

    PPA v2 construction discussion

    In Tangent's guide it says: "If you have a dual-voltage power supply, it's probably better to run the amp from the outer terminals and ignore the ground lead than to try and hook up the ground lead"   Doesen't this mean that i can do what I asked about above?   If I understand...

    So, can I connect the + connector on my PSU to V+ on the PPA, and the - connector to V- on the PPA and just ignore the G connector on my PSU?
