Presenting thread HERE

Schematic and pcb screenshot post #2 , plenty o pictures after .

Reading entire thread is advisable , same as inquiring any technical question there : Be sure that you are aware of all things electrical and mechanical !

Pcbs are not made for UMS (don't care, don't want) , mounting either on 30mmx50mm L bracket , or directly to heatsink (will show you how) , where even two bolts through mosfets are enough to hold entire shebang in place. Do not hurry - read , think , ask and only when you feel that you want it and can make it , proceed ...... advice which I'm finding applicable on practically anything


For anything else , write either here , send PM or directly to >zenmodiyaudio@gmail.com<

Prices are mostly dictated with small scale nature of operation (as always is case) and time/work involved in matching and soldering little buggers.

For ordering , contact me at above written e-mail addy .





Kit options :


1.
- LCH pcb ,
- RCH pcb ,
- all smd buffer JFets presoldered ,
- Hall current sensing chips presoldered ,
- surrounding smd caps presoldered ,
- 2pcs of 1uF MKC caps (for critical signal position) enclosed.

Full price , including Paypal fee and P&P for registered shipping all around the Globe - 130E

2.
- LCH pcb ,
- RCH pcb ,
- all smd buffer JFets presoldered ,
- Hall current sensing chips presoldered ,
- surrounding smd caps presoldered ,
- 2pcs of 1uF MKC caps (for critical signal position) enclosed.
-all multiturn trimpots
-output mosfets , 4 pcs , (I'm working on availability of Harris 9240 , but I like Vishay there)
-voltage regs
-cascode bjts
-optocouplers
-all electrolytic caps (Pana , working on availability of Silmic II for 1 position)
-one-pin sockets for special resistor positions
-mica
-all (MF 600mW) resistors

to recapitulate - everything what goes on pcbs , excluding signal xformers and pcb/mosfet mounting screws/nuts/washers

Full price , including Paypal fee and P&P for registered shipping all around the Globe - 175E



If I have everything in drawers in moment of order , can ship in 3-5 days ;
If I don't have any of normal parts in drawer , shipping could be delayed up to 3 days;
If I don't have pcbs in drawer , shipping could be delayed up to 7 days;
If I don't have most critical part for getting in my neck of wood - ACS Hall chips , shipping could be delayed up to 3 weeks.

edit , few days later - no Harris IRFP9240 , but resorted to Infineon IRFP9140

EDIT: final iteration of pcbs matched to DiyAudio UMS , final schm and pcb sshot posted in #118, Babelfish M25 , AKA M2 on steroids , AKA M2-XA25 bstrd

Thanks, been waiting. Would like Harris mosfets if possible, otherwise I have extra set from TEABAG for his M2 kit. Those kits are one IRF and one Harris, one that has measurement oddity, which I really never noticed.

I would like all Harris just for better sleep purposes.

Any future chance of smaller daughter board to convert existing M2 clones to berserk unconstipated M25?



Advise,

Russellc

Let me know when you feel you are ready with package #2 with Harris 9240 and Silmic II.

Best regards

Russel - that could be too complicated

observe changed optocoupler type , and - considering what I did to optimize power routes on pcb , adding any daughter board to (any) existing pcb would result in less than optimal final package ..... simply , too much to change in existing M2 , too many traces to cut and too many small wires to route ;

Waiting for answer from my regular vendors about non-Vishay . Though - as I said , I like Vishay in that position ..... not trying to make surgical instrument , I'm more for Pleasure Devices

Verdict - will not invest insane amount of energy and resources in that issue , which is non-issue for me .

Silmic II , pretty much solved .

Quantity of Hall chips ordered , will get them as soon I'm back from Mountain



edit: to paraphrase Russell - all Vishay ....... is for sweeter sleep purposes

I figured as much. Well when all is ready with Similic and Harris, I'm good to go, or as stated with Tea's outputs.

in this moment , I have information that Harris is possible , but not exactly fully trustworthy source

will finally know tomorrow ;

anyway , one thing - why I'm so relaxed regarding Harris or no issue - this is source follower , where that problem is much lesser than in case of F5 , for instance

(common drain vs. common source , variable capacitance is not exactly same variable in different arrangements)

so , no biggie
