I have the same problem where one of my buffers gets hot enough to hurt me if I touched it.  I know I installed one of them in reverse and I think on a different one there was a bridged solder joint and after I corrected it then one gets hot so they're probably fried or something.  I'm using the...

Whoops I see the mistake! BufL is reversed...lol.  I guess was paying more attention to putting on the right amount of thermal paste than the direction.  Now to try desoldering it and see if it's salvageable

There is an external power supply (an acopian 24v linear regulated) being fed into the pimeta.  The battery pack has not been constructed yet (planning to use 10-14 2500mah AA nimh depending how they fit in the case).  I was going to do that when it came time to case it.  C1 is jumpered.  It's...

I had 11.6v on the V+ and V- of both opamp sockets prior to installing any opamps or buffers.  Once I install the opamps and buffers I check and the rail voltage was like 19 on the V+ and 1.9 on the V- of both opamps. The buffers were hot too.  I went back and cleaned up my soldering around the...

The dc offset with lme49860 was ~0-1 both channels, ad8599 was ~1/3, lt1364 was 36mV but I figured that was safe with only 32ohm impedance. I gave ad8610 a quick listen and it was pretty bad. opa627 otoh is by far the best. nothing else I've used is anywhere close. This is with a modded x-fi...

Can I use my opa627 and ad8610 on adapters and ad823 which I bought for my pimeta v2 safely in my little dot I+? I read somewhere that fet input opamps are more fragile so I don't want to kill them. I've tried lt1364, lme49860, opa227, ad8599, and opa2132 I would have to say I prefer the opa2132...

I would like to mod an ipod touch 1g (or 2g/3g if possible) as seen on http://www.head-fi.org/forums/f43/fs...-415-a-424968/ I've searched high and low for any info on this but have come up totally empty and the OP is banned. Can anyone help me out? **EDIT** Found the actual explanation...

Anyone got some Japanese Ocarina (ala Karate Kid music) recommendations?

I just tried this record player out that my dad gave me. It hasn't been used in a long time. I listened to one side of a record and about half way through the 2nd side the right channel went dead. I shut it off for the day and came back a day later and it worked for a whole side of a record then...

Oh yeah. Sorry. I forgot about the second issue I have. Which caps would be best for power supply rails. Assuming I can use the +/-12v supply/15xAA nimh. The tallest caps my enclosure can hold are 34mm. I'm considering these which are available on mouser: 3x 647-UHD1H681MHD 680uf 50v...

I have a +/-12v dual regulated supply that is lying around. I checked to see if it's isolated and I think it is. Is it possible to use a dual supply with a pimeta that also has nimh batteries? Do I just keep TLE2426 as designed and connect the V+ and V- and leave ground unconnected or would...

If the chemical had gone bad I would think it would have reacted with the other records I used it on but maybe not. The other possibility is that I just filled the grooves with dust and the needle is digging it out as it plays. This seems like it might be possible since I can see what looks like...
