    no that’s a Monoprice collaboration. I want a CEE TEE resurrection of the original.

    I agree the monoprice LP lost something in translation.

    You can add me as well now

    Mind helping me out? I see the "230V jumper" tag but not sure whats supose to be done with those wires instead since it doesnt look like a jumper.....

    [​IMG]

    Also, any idea what fuse I shoud use? Looks like a 20mm and its T1250V and looks like a quick blow, so I would assume T2250V shot blow to replace it but wasnt sure.

    Re the 230V, did you get this from Europe or are you in Europe?

    The transformer will have 2 pairs of primaries, wired in parallel for the US and in series for 230.

    Fuse, both should be the same, a guess would be 1 to 2 A, it probably has the details in the manual.

    Got from europe and am in the US. With the brown and the black, which color goes with which? Figure doing them backwards would be pretty bad.....

    Unfortunately no mention of the fuse in the manual either :/

    This wiring color looks different, send me a similar picture to this one so that I can see the blue/white brown/black wire going from the transformer to the connections

    Looks like they wrapped the pairs the other way between my unit and the one in your picture. Looks like the wires are hooked to the transformer the same way though

    So the bottom 2 tabs are tying the middle (of the primaries, black & brown) together like a centertap, and that row isn't on Live or N from the socket, which makes it in series. If you instead tie blue & black and white/brown together on ac1/2 which must be L/N that would be in parallel. Main difference is on the euro one they twist the 2 endpoints and the 2 middle points together and on the other they are twisting that side of the primary together.

    Agreed with above, to make sure you keep the phase correct, make sure white and brown go to ac1 and blue / black go to ac2

    Sounds good. Ill get the leads moved over at lunch in just a few. I am pretty comfortable with a multi-meter. How should I go about probing this thing to make sure I dont blow up the transformer?

    You would have to remove the input wires to the amp and measure the output of the secondaries. BUT , i don't think this is necessary and if you rewind and relocate the wires as described, then you will be good to go. No risk to transformer here , biggest risk is to amp but it is greater risk when living in 230V area than an 115V area.

    if you plug a device wired for 115V into 230V = you get MUCH more voltage out than you want, if you do the reverse, you get half the voltage and the circuit just won't work optimally.

    this will all work out and hopefully you will have a fantastic amp making sound soon.

    Well those spades were a right pain in the ass to get off. No slack and super close together. Once I got them off you could see the pin markings

    [​IMG]

    I currently have it

    Pin 3: White. Pin 4: Brown
    Pin 1: Black. Pin 2: Blue

    Does this look right?

    looks good

    edit

    only thing you might consider is winding the 2 common secondaries together - Brown Blue twisted and white black twisted together.

    - it wont explode or damage the amp the way it is but might offer some additional noise rejection

    holy f**k is this good. Just..... holy f**k..... Like I know I'm a tube guy but without the 13R on hand I dont even think its a close race in terms of subjective prefrence here (will need to see if that holds up once I get the 13R back from repair)

    ah, I didnt even think of noise rejection. I guess I'll fix that at some point (maybe once my new amp arrives). TYVM for the heads up

    Still pad rolling and testing the he-6. It changes presentation quite a bit with pads. Veli pads = mini susvara with a hair more aggression in the bass (especialy prevalent with stiff like infected mushroom). Audeze vegan = audeze presentation with hifiman tonality (very very interesting tbh. It's like an he1000 SE and LCD-4 has a baby). Over all I don't have another amp to test them on currently but I think the LC is running out of a bit of steam with the he-6 tbh giving me too bass texture but not giving me the proper sharp leading edge of the slam like I know he6 can give. This is using a 70s Philips harleen ecc88 fwiw.

    I wouldn't really say that is "lack of steam", it's more of its characteristic, it's a more texture/nuances amp than slam focused amp.
