i hate every single one of you.
except for jahn who posted those awsome links, no exceptions.
the left chanel on my melos can also suck my caulk and bulls.

at least i wont be lacking work until my parts get here.

the right chanel is good enough for ety er4s's. the left isnt even THAT bad, but its there. argh.

Now I'm starting to see why no one's tried to tame this beast since Carlo. My lord.

If you're going to re-route it please provide pics as I will do the same. Good luck man.


edit: turns out I didn't get too great of a deal. They charged me $25 shipping via UPS ground for a 2.9 pound package. Talk about taking the bait - should have known a $74 price brand new was too good to be true. Bastards.

i will when i get about to doing it. my digital camera does suck, so i may just give a detailed writeup.

hello headfi.

that was a wonderfull expendature of about 20 minutes. left chanel mod performed, and the noise is almost 100% gone. there is a very soft hiss that a non audiophile would not hear.... for people who normally listne loud, it could easily be confused for a "black" backround. at LOW levels it is very quiet.

(rant mode on)
why the fack was this board layed-out the way it was? the HV goes from the input on the left through a rectifyer, into a cap, into a resistor, into another cap. from here a "mildly filtered" signal CROSSES the entire board right across the middle to the "ss cleansing stage" after which it CROSSES the WHOLE way back across (actually more than the dirty cross) to another cap and then half way across the board to the actual tubes.

whoever designed this amp's board could have done a mucho better job. for examples, look at the stax brand amps. even the ones of similar vintage to this one. EVERYHTING is kept well sepperated and actually marked (gasp!) the power "filtering" section actually has a silk-screened line around it and a buffer zone of about 1cm between ANYTHIGN else!
(/rant off)

do the following at your own risk, and at risk to your likely irreplacable amp.

anyways, to do this what you do is as follows:
locate the 2 transistors above the interstage caps. there are 2.
the LEFT one (on the side of the baord with the HV caps) is the one to look at. direecetly above it is a 2-k-ohm resistor.
flip the board over and find the TOP of that resistor (closer to the back of the case)
from here you will see an "s" shaped trace that parallels (fackers) one of the HV lines.
follow this trace upto the mosfet. it is the mosfet closer to the back of the case, and the pin is the pin closest to the top of the case.
unsolder the 2-k-ohm resistor.
cut the trace close to the mosfet close to the mosfet. there is a big open bit of board space, so just go to town with an exacto knife.
solder the resistor to the UNDERSIDE of the board. it needs to go in the hole CLOSER to the transistor.
solder a wire from the resistors free end to the mosfet's pin which you clipped.

NOTE: the mosfet's pin has 2 traces on it. one goes into a diferent resistor and diode closer to the top of the board, dont cut this one.

enjoy.

how long does partsconnexion usually take to process an order? i put my order in on sunday and have gotten no reply/billing.

ooh, the melos works well with my frankengrados (highly modifyed sr-125) too. the hp1000 are in storage tepmorarily, as they have stollen the play time from EVERY other headphone i own.

My experience has been under 8 hours. Usually closer to 4 if they have the stuff in stock. You may want to call them.

I had a couple of emails from Vikki on Saturday night/Sunday morning (1 something in the morning and the second around 5:30 Sunday morning). She said they had gotten 150 orders plus 100 quotes, and to please be patient. I had placed my order on Friday afternoon, and have not yet gotten a shipping confirmation. My order had a sh*&load of resistors on it, so probably not the easiest thing to pick , and probably ensures mine will be one of the last to ship. They are a small operation, so this probably swamped them.

haha no way! use the HP1000 to tweak your amp while modding! if you read the reviews on that can in the downloads i linked, some engineers said they used the HP1000 for tweaking their studio gear because it was so spot on and caught everything you need to hear - crazy!

i am, but they steal the show from everything else.
i must rotate headphones, or they will get jelous.

was i the only one at the Summer NYC Meet to try on the Frankengrados? they were actually pretty darn fun as I recall, I was very impressed!

i think siburning tried them too. short of putting them on peoples heads i didnt expect them to get much playtime.

they actually do SOMETHING better than the hp1000. soundstage is a big one.

My soldering iron better get here tomorrow - that way I can enjoy an auricapped/partially blackgated melos over the long weekend!

you may want to just put the auricaps in for the weekend. black gates take a week and a day to breakin, and often sound like bad until they do.

plus this gives you more to do, spread over a longer time

i hope my blackgates get here with time to burn in for the meet.

I figure I might as well start them burning in now though - in case I can actually finish in time for the meet. I need to get some crappy tubes I can leave running while I'm at class....any suggestions for cheap yet decent sounding ones?
