Wayne's headamp for Kiddo

Have a Nephew moving to States in few days ,he was there for a year or so and succeeded in complicating own life , falling in love in Florida :rofl:

So , I promised to make him head-amp to bring with him.

'nuff said , except - Kudos and Thank You - to Wayne , straightforward and easy , of course that you can't expect anything else from Funny Firm :)

My build is , in fact , pretty much quick'n'dirty approach - changes on the fly .... somewhere smaller caps , somewhere larger caps, regs ditto to 15V (Donut is dual primary wired for 115Vac , but secs are nominally 15Vac) , pot is clickety 220Klin jobbie , shunted with 33K so pretty nice log law with precise channel balance ... old heatsinks , raw case etc.

sound is good , everything stable , no problems

believe it or not , Al knob (4mm shaft , so that causing troubles with knob choice ) is from olde Korting A100 integrated

hm, even mentioned 220Klin pot is from same amp , superduper quality , seen low action , being either treble or bass

salvaged several of these amps during the years , mostly as trash bin parts donors

however , they had nice potted Donuts (one per amp) and 2 of these are proudly powering my DEFiSIT now

:clown:

will change vol button for something nicer , as soon I find where I left small bag of 4 to 6 shaft adapters (sleeve, practically)
 
It is strange Alps does not make these BB anymore if they are a class better than the Blue. The only pot that seems to be above the blue it this one:
RK501 Series - Basic information
I have never seen it in real use. From picture it looks expensive. Only available in 100k it seems.

Good lord! A $400 pot? It would go well with some $1k speaker and interconnect cables...

that funny looking "DACT type"** thingie is worth every cent , I hear

speaking of resistive attenuators , that's it ..... and I either had them or still have them all , worth having

if you want to go Berserk , AVC is the way , though to some not worth greenies and hassle

for me , it is way of solving few things with one stroke

**search for exact term on fleabay
