re-no posts

... well it seems the FF was updating - i donno there's constant problems with Google such as youtube, blogger, Plus, you name it - so it might have been either or both in symbiosis causing the prev. blogger hang - not my job - i just try to pass some typos here :p

so while i didn't ::

(2) a 12V demo TTL stage
(3) 6V 2.7A supply dev.
(4) a TEST suply dev
(5) UV-LED LDO supply develpment , (1) improved the TF matching on a go , (2) reached a barely working instance of (5) after multiple REAL WORLD tests and redesigns (the cause of the prev. A_L_E_R_T post)

(6) 9V Creative 2x Spk supply (it's amazing it vas fed directly from ~5VAC adapter - 0 to 10V peak - peak - had a real nasty hum B-coz of F;Y) - same as prev. - reached a working instance - but some features not necessary - so re-designed:
(7) ++ TF-1k14mW8k66mV131mA-TEST-03.asc (not yet been built) :: some dev. stages:
(a) ~38VAC►Filter►near 16V shunting reg.►Filter with 16V Lytes►9V LDO
(b) ~38VAC►Filter►near 16V LDO based on LM78L12.►Filter with 16V Lytes►9V LDO -- both the 2 resistor Vout extention scheme AND TL431 VoXs showed nasty dependency on Vin - so this design was discarded
(c) ~38VAC►Filter►near 16V LDO based on analog.(from)►Filter►9V LDO ...

(8) not directly simulation stuff + other stuff (outside the scope of this blog)

Fig. 4 (7):
/!\ -- the 16V pre-conditioner has NOT been built in practice yet -- /!\it's quite likely i've 2-Z some shunting resistance before and after the 317 to keep the pre-voltage below 36V at no load . . . why not22 so @ the 1-st place - is B-coz we won't learn anything then
