Does anyone happen to have the values for Hammond 1182J22 - 50VA 22Vx2 ?

 

[Monk55]

Toroidy TS500VA Audio grade 120v primary, dual 18v secondary’s:
Cx- .01uf
Cs- .15uf
RS- 27 ohm (both)

 

[Monk55]

After re-doing RS-12.7 ohm..Qmodo U2 failed had to put in a new one.

 

[elwood625]

Antek AS-0515
50va dual 15v secondaries
Cx = 0.01uf
Cs = 0.15uf
Rs = 50 ohms and 51 ohms on the other secondary
Antek AS-0532
50va dual 32v secondaries
Cx = 0.01uf
Cs = 0.15uf
Rs = 84.4 ohms and 88 ohms

Both tested with 110v primaries shorted

Hammond 229B56

Cx 10nF
Cs 150nF
Rs 480Ω

What's the recommended wattage rating of the 480ohm resistor? Does it need to be 2-3w, or will .5w work?

 

[Monk55]

.5 will work. What ever you have after that. I had 1w in the box.Note: redid primary wiring...

Rejdr,

Try this. I think Mark Johnson put this up a while ago.
Short version - 0.5W is probably fine.

 

[redjr]

Thanks. I'll have a look.

I used 1W

Does anyone have the values for Triad VPT230-220 and VPT24-2080?

 

[ScottManske]

Good info here...does anyone have a suggested for values on a Hammond 1182u24, building my first diy PSU v3 and F5 turbo mono blocks...any insight is appreciated. Looking for Cx, Cs and Rs, noting I am running 120vac on the line side, 24v secondaries on the transformer.

Anybody done the test for a Hammond 229C24 and 229C30?

 

[Bensen]

Here are the results for the hammond 229C40.Quasimodo results (ONLY)

Can I for the same VA type xfmr (229C), lineair interpolate the Quasimodo Rs value for other output voltages?

E.g.
- 229C40 ==> Rs= 577R
- 229C24 ==> Rs= 577* 24/40

Hicoco, thanks so much for result for 229C16.
Is Rs value of 72R for each secondary?
If yes, can you please give us Rs value for connection of both secondaries in parallel.
Thanks in advance

 

[Hicoco]

Hammond 229C16

Same Value (72R) for each secondary and for both secondaries in parallel.
That is the graph of the both secondaries in parallel.
