My PPA has been in storage for a while and I pulled it out to use. The epsilon 12 in it was oscillating on the relay, switching it on and off. I remembered this being an adjustment issue, so I popped it open and started working the trimpot. Unfortunately, the only stable state I can get it into...

I was looking at upcoming shows at a local venue and came across Bernadette Seacrest. When looking at her website, I found that she has basically two albums up for free. The newer one doesn't appear to be an official album yet, but I like it. Very nice voice - it's very Madeleine Peyroux. The...

My wife and I will be in Prague in the near future for the wedding of a close friend. We're reading up on things to do, but I thought I would consult the forum group-mind. This forum in particular has a good number of European members and probably several living in Prague. Anyone have...

Anyone here into Rai music? The only album I have at the moment is Cheb Mami's "Meli Meli", which I enjoy a lot. Khaled is the obvious other artist to check out, but he (and Mami) has a lot of albums and there seem to be splits between reviews of people preferring older versus newer work. Any...

After trying several different headphones, I really clicked with the DT880 and enjoy them greatly. I own nice speakers (currently Ascend Acoustic Sierra-1's) and have heard a lot (I go to the Rocky Mountain Audio Fest each year), but I'm curious to hear what people think are the speakers closest...

I just finished re-wiring my PPA/STEPS combo. I was never very happy with the cleanliness of my initial wiring, so I redid everything to make it cleaner, added one of AMB's epsilon 12s and a DC output jack. I wanted to make better use of the STEPS in the PPA, so I made a switchable DC output...

I'm rewiring my PPA with built-in STEP and I'm putting separate power LED's on the STEP and PPA (I'm adding a switch in the back to switch the STEP output from the PPA to a DC output jack so I can power other amps off the STEP if I want). I already have a nice FPE front panel that I don't want...

I've had a PPA for a while now that I built (1.x board with Glassman buffers) and have enjoyed with my HD-600s. Recently, I picked up some SR-225s to have my choice of sounds. When using the 225s with the PPA, I get an odd buzzing noise. The noise doesn't get louder with the volume, is present...

I recently purchased an Echo Audio Indigo IO and I have to say that it does an impressive job driving my HD-600s (and my ER-6s, but I'm less impressed by that accomplishment). I haven't spent time doing direct comparisons to my pretty maxed PPA, but I could certainly be happy with the Indigo...

I just finished hooking up my PPA in my new case. I tested it before installing it - worked fine. I tested it after installing it - worked fine. I tested it after connecting the input ground to the case - no sound at all. I detached the input ground from the case - works fine. I removed the...

It isn't as cool as doobooloo's new creation, but I finished most of my casing today and thought I would share pics. None of the signal wiring is done yet, pending receiving my group buy silver wire. The PPA board itself isn't screwed down yet either - I need to pick up some longer #4 screws. At...

I figured I would start a thread about building ICs with the silver wire from the group buy. A place to talk about choices for connectors, wire configurations and other stuff. I haven't received mine yet, but I'm thinking of making a pair using a three wire basic braid (two for return, one...

I have changed my mind and decided to add a bass boost to the PPA I am building (it's done except for the casing). Unfortunately, I didn't order any of the BC 416 0.1uF caps and it isn't worth ordering just those. I do have two options lying around (nearly identical options): 1) 0.1uF...

I'm putting together my PPA and took a chance on the new knobs that DIYcable carries now. At $8 and $13 they are pretty reasonably priced (when talking about solid metal knobs at least). They are a very nice bead-blaster solid aluminum - I'm quite happy with them and can't wait for the rest of...

I am considering using a bulgin switch in the PPA I am building (just the regular, non-lighted version) and I was looking through stuff for a relay circuit. I found Wooderson's thread on his PPA with Bulgin that included a referenced schematic...

I finished my PPA and STEPs this weekend (no case yet, I still have to order my Par-Metal). They both seem to work fine, except for a buzz the can't be heard until the volume is about half way up (and gets louder as you increase the volume further). It is present either when an input is attached...

I just received a pair of AudioTechnica ATH-A900 headphones that I bought off a fellow head-fier. I sat down for a while this evening to compare them with my existing phones, Sennheiser HD-600s (stock, also bought used from a fellow head-fier). I played some of my standard auditioning tracks...

I am ordering parts for building a PPA and was about to order a Par Metal case only to find that their website (http://www.par-metal.com) was down for a couple of days and now it is back up, but is a different company that does completely different things. Is ParMetal gone? If so, any...

Does anyone have saved files for Front Panel Express panels for a PPA in the standard Hammond case that they would share? While I understand a lot of work may go into doing these right and some folks here do PPA work as a side business, it would be great to have a starting point with the basics...

I've had Sony MDR-EX71s for a couple of months now (got them when I got my iRiver H-120) and I have used them mostly on my iRiver, but some on my computer. I also own HD-600s and SR-80s (just sold the 80s to make room for the ER-6s) and a couple others. I was bothered by a very slight hiss in...

I was browsing DIY audio sites and found that Hagerman Tech has a 'half kit' (like Tangent and the META42) for a power supply (http://www.hagtech.com/bugle.html#powersupply). It's meant for their phono pre-amp, but provides 15 VDC using a toroidal transformer on a nice PCB. It seems like a...
