Quasimodo results (ONLY)

[thompsontechs]

Do a search earlier in the thread, there are some models close to yours which may get you in the ballpark.

Antek AS-4218, 400VA, dual 18V secondaries, dual full wave bridges:
(Attributed to another DIYer who requested to not use his name.)



Cx = 3.3nf
Cs = 470nf
Rs = 16.9 ohms

 

[ItsAllInMyHead]

Antek AN-0112

Cx = 0.01uF
Cs = 0.15uF

CT Configuration - 24 ohms
Dual Secondary Configuration = 34 ohms

Antek AN-0115

Cx = 0.01uF
Cs = 0.15uF

CT Configuration - 30 ohms
Dual Secondary Configuration = 40 ohms

Note - I don't include additional significant digits / fractions of ohms. I get it close enough and err on the higher side for resistance.

Signal Transformer DPC-24-450 // PC mount transformer // 10VA // dual primary // dual secondary: 2 x 12VAC

------------

CONFIGURATION 1: SEPARATE SECONDARIES (12VAC to DiodeBridge1 , 12VAC to DiodeBridge2)
OPTIMIZED SNUBBER FOR EACH SECONDARY
Cx = 10 nF
Cs = 150 nF
Rs = 120 ohms

------------

CONFIGURATION 2: SECONDARIES CONNECTED IN SERIES (24VAC to OnlyDiodeBridge)
OPTIMIZED SNUBBER TO USE ACROSS THE 24VAC SERIES CONNECTION
Cx = 10 nF
Cs = 150 nF
Rs = 215 ohms

------------

CONFIGURATION 3: SECONDARIES CONNECTED IN SERIES (24VAC) AND
WEIRD/UNUSUAL CAPACITOR VALUES. WHY? FOR FUN OF COURSE.
Cx = 680 pF (0.68 nF)
Cs = 1.5 uF (1500 nF)
Rs = 740 ohms

AnTek AS-0518
2X18V 50VA
Cx = .01uF
Cs = .15uF
Rs = 44.2Ω

 

[Monk55]

Antek AS-4435
2x35v (only did 35v secondary)
Cx .01uf
Cs .15uf
R 15.6…..I used 18ohm

 

[freebee]

Hammond 229B40
2x 20v
Cx .01uf
Cs 10uf
Rs 92ohm

Does someone have Quasimodo values for Myrra 45061, 30VA, 2x6V, primary 2x115V?

What Rs value would be good to put there if I use Cx = 10 nF, Cs = 150 nF?

I do not have any Quasimodo test jig or oscilloscope.

 

[freebee]

Toroidy TS250VA
Pri: 230V
S1: 2x14V
S2: 2x14V

Cx = 10 nF
Cs = 150 nF
Rs = 12 ohms

 

[trobbins]

AMPEG 300726-1 (as used in VT series amps from late 1970's)
450Vac winding
Cx = 10 nF
Cs = 100 nF
Rs = 610 ohms
