Update..... Will have the top and rear panels cut and polished soon.      
Hi Dejan,Misterrogers is spot on.  Has nothing to do with the PCB.  It's all about the output transformers.  The windings and resistor values you specify to match your headphone and speaker specs.  If you only want to use HP's have the OPT's made to match.  Mine are  Audeze LCD2 and  MTL speakers with Alpair drivers. I'm building a case for Misterrogers DG300B. Why?   Cuz I didn't build my case and I wanted to see if I could build a better one.  Unfinished woodworking...
hey!   Hope everyone is having a fine new year. I was contacted by a new friend that also built the Tom Christensen's DG300B amp....  well we got to talking and it seems Mike didn't have a case for it.   Hmm?  The case is the one thing I did not make for my 300B.  I considered it "unfinished business" and had to build one.  I've done some contouring/sculpting on other projects and liked the results.  I decided to make an "organic" variation of mine.    In birds eye...
My son has undertaken to build Tom Christiansen's (Neurochrome), solid state Modulus86 amplifier and differential pre-amp.  He has completed most of the boards and has started the Douglas Self (Signal Transfer Company) balanced phono preamp and power supply.   In my DG300b setup I paired Self's preamp with a Rega RP3/Exact cart combo.   To my ears, it sounds sublime.    Since he's getting close I have started on the "enclosure", so-to-speak.   Grant hinted that he...
Thanks.The speakers are a Mass Loaded Transmission Line design from Bob Brines. The cabinets are solid 4/4 quilted maple.  I am delighted with how they sound.  It's magic where, to my ears, the base comes from.
she's a done.          
I completed building the Douglas Self RIAA differential phono preamp and power supply.  I also built a separate differential preamp for the DB300B.   Happy to report that everything tested well, so I purchased a Rega RP3  turntable with a Rega Exact MM cartridge.   I am delighted with the results.   All I have to do is put the preamp boards into the 300B.  The phono stuff will stay external in Hammond Cases.  At the same time I am building a table for everything.  The...
Dropping the price to $160
I have owned a Sonance multi-channel amp for almost ten years.  It distributes stereo to 6 rooms in my house  (12 speakers)   Model 1250 MkII   My in-wall speakers are Paradigm.   All you need is a small Schiit DAC for your iPod and you are good to go.
I have always used Multicore / Loc 0.5mm 5 core.    I get great results.  I learned to solder SMD using Dave Jones (EEVBLOG) 3 part tutorial. This is the solder Dave recommends.  SMD is not a problem.  I can't imagine that some exotic or solder with say Ag would make much sonic of a difference.   My son had limited soldering experience.  After watching the tutorial, he's building a dense SMD differential preamp.
