Thanks tangent.  I'm going to change R1 and R2 to higher values.  Hopefully I'll have the amp all cased up by the end of the weekend.  Its going into a translucent grey serpac H65.

I have a question about resistor values used in the pimeta.  After I failed to get my pimeta running from a dual supply I decided to go in another direction.  I'm using R1 and R2 as a voltage divider to drop the incoming audio signal around 30 decibels and from there I adjust volume digitally...

I've been trying to figure out how to run the pimeta from a dual supply.  I have 2 12v sla batteries that I connect in series to run an amp for my speakers.  For some reason I only recently used the batteries in series to power my pimeta.  Everything worked fine and I tried to find...

Headroom is selling the HD650 for $349 shipped.  They are listed at $499 on website but if you use coupon code hd650 the price drops to $349, you can also call them up and get the same price on the phone.  I just bought them 6 days ago from headroom and couldn't be happier.  The price was $30...

I bought the same headphones at the same place about 2 months ago.  Mine made that same clicking noise from the adjustment area when I would swivel the earcups.  They don't make the clicking noise anymore.  I can't remember how it took them to stop either, in fact I forgot all about it until I...

Just finished my pimeta. I only have a couple of hours of listening time on it but i'm loving it. I've only heard this amp and a cmoy I built and i'm really impressed with how good music sounds at low volumes with this amp. I can't believe there is so much impact at low volume levels. I...

I just remeasured the voltages and on OPALR and OPAG and got 4.09 for V+ and -4.09 for V-. I used a different spot the board to measure the input ground IG. This time I used the area in the scratchpad marked IG. Previously I was measuring from where the input ground IG is right by IL and IR...

I'm not getting the correct values when testing the power supply in step 11 of the step by step assembly guide. It appears the voltage isn't being split. Here are the voltages I'm getting with a slightly used 9v battery: OPALR V- -8.77 V+ -.56 OPAG V- -8.77 V+ -.56 TLE2426 COM -8.77 OUT -4.66...

BFG LS series has gotten some really good reviews. I recently upgraded from a 3 year old OCZ 520ADJ SLI PSU to a BFG MX680 modular PSU. The BFG MX series is just a modular version of the LS series. The effect on audio has been outstanding, bass, sound clarity and soundstage all increased. The...
