3D printed ”pad holder” today. The grey thing attached to the driver unit with six screws. SR-007 ear pad in place. Then take the package and push it into the frame – done. Found a piece of aluminum net and with some black paint it will serve as grill. Exposed cable connections. Have to fix that some time.

Damn, that sounds nice. Wait, that makes no sense, I’m not there.

Happy Birthday, Shelly

Happy birthday Shell! Have a great one with your lady love. Cheers!

Thanks Purk... I appreciate it! Sent from my iPhone using Tapatalk

He/She will love it Chris. Hard to beat the Mini Dynalo. I have the GSX Mini on loan from Justin and I'm splitting hair to hear difference. Thank you so much for making one for me.

Considering the number of views, some of you guys have probably seen this.

Firstly many thanks to all the contributors to this forum whos posts and direct assistance helped immensely with my amp build, there were a few issues on the way, but the amp is functioning perfectly and is a huge improvement over the STM-727II it replaces. There are many far more seasoned builders than I, but hopefully by mentioning a couple of issues I encountered it may help any future builders. 1) Check and double check your resistor values - I missed one and it resulted in quite a few replacement parts being needed. 2) If you are going to check voltages using your probe on the top of the screw terminals, tighten the screw down first (changed out the original 7815 regulator thinking it was faulty as a result) 3) You need the OP27 opamp installed even if you are using the opto servo to control offset. 4) The posted instructions mention adjusting the left channel balance and offset - you also need to perform the same operation on the right channel 5) I bought an inexpensive set of high voltage 12kv linesmans gloves from Amazon. Probably overkill but for the initial power up of the boards gave me more confidence in working with HV supplies. 6) Mentioned in another thread but Arrow Electronics offer most parts that Mouser have at lower cost and with free overnight shipping 7) If you need circuit boards, Easy EDA is pretty good at circuit layout and integrates with board manufacturer JLCPCB who are really inexpensive (read $2 for 5 small boards) Differences from what I would consider as standard build included: Replaced the 7815 and 7915 with AMB Labs Sigma 78 and Sigma 79 drop in circuits - soldering on the miniscule SM components is a challenge but aside from that they work really well. Used a ladder attenuator from Acoustic Dimensions, made a custom PCB to connect to it (I have 3 spares if anyone needs one). Installed input switching between single end and balanced, with also a feed through setting where the KGSSHV is totally bypassed. The SE input setting also connects the SE ground to the amps -ve balanced input. Picture is the KGSSHV Carbon with it's sibling a TPA Buffalo ESS9035 DAC built last year. Cheers Martin

Then I can sell my Stax phones. Considering the price level for used stuff I might capitalize them and buy myself a Mercedes Benz.

Definitely not a mash up. Now I've seen Paul Simon perform this live (with Sting singing backing vocals). But this is better. In fact the best IMO

Where's the restart button?
