If you change your power cable don't forget to test the phase with your tongue.

What will be the size of BH board ? I have a chassis in stock I would like to know if a BH can fit in

I hade the banned screen 4 or 5 times on my phone on 4G (without be logged in) and once on my PC. It started around the end of December. I tried to clear my cookie or changed the browser nothing works. I just waited a couple of minutes and it works again.

Thx for the GB, I am interessted by megatron but I think I am the only one

I miss Hifiman, HE-5, HE-500, HE-6, these cans changed the game. At first I thought it was a passionate brand.

What is this pot ? It seems to be an old linear potentiometer

" Due to the need for DSP to achieve the target frequency response, all incoming analog signals must first be converted to digital. This is undertaken in a multi-channel 32-bit/384 kHz AKM Premium ADC chip. " https://sonomaacoustics.com/technology/ Analog -> digital -> analog -> trash

Do you know if there is a PCB version with heathink offboard ? Thank you

I forgot to thank you. I don't have 150k resistance in stock, anyway I need to order some components from mouser, I will do the mod on my return from vacation. Do you have any idea why the amp has a second version ?

The main board changed too. EDIT: here is the 301 picture found on Head-fi, no more C41 C42 C44 C45 and some strange cables on the 302

I think I will mod my 727A. I open the amp but my board are a bit different, I think it's only aesthetic. On Spritzer's picture, the boards are flocked "PB-301" on mine it's "PB-302" is there any difference ?

http://www.goodcomponent.com/ This shop is nice ! You can find: teflon socket, OCC coper, nice transformer cover, .... and the price is quite good. You can find this shop on ebay too, but their price are higher over there.

Thank you for your answer, I think I will use this PCB http://www.ebay.com/itm/10pc-CMC-9pin-tube-socket-Adapter-bare-PCB-for-EL84-12AX7-6BQ5-ECC83-ECC85-6P14-/191208473634?hash=item2c84e9c422:g:slcAAOxyUfFTlc8q This socket www.ebay.com/itm/1PC-High-Quality-Ceramic-9Pin-B9A-Vacuum-Tube-Socket-For-12BH7-12AU7-ECC83-EL84-/191688017575?hash=item2ca17f06a7:g:ZkAAAOSw5dNWmODJ Fix everything to the chassis with this http://www.ebay.com/itm/2PCS-34mm-12AU7-Vintage-Tube-Audio-Matting-Machined-Aluminum-Decorative-Ring-DIY-/201496427354?hash=item2eea1f7b5a:g:eX0AAOSwKtlWij~P And wire the tube pcb to the KGST pcb with a molex connector as you did

My board was not design to put the tubes on the underside, and the 6S4A is a 9 pins socket, I can't flip it with the same layout

thank you I think last question, Can I flip all component on the other side of the boards to get the tube almost alone on one side ? All component exept no flipable component like the lsk389 or the STN9360
