power supply help :how to sum voltages on a trans

[scottericsonon]

im just getting started building tube stuff and have run into a problem with a transformer i was hoping to use

this is non-audio but it shouldnt make a difference right??

i'm hoping to build a RF amplifier <i have a ham radio license> with a pair of 6146B tubes

the tranny i have came out of a junk radio running the same tubes so i know it is capable but not sure how to get the voltages i need

it has 2 110V primarys bridged together and secondaries that are as listed running down the oppisite side of the trans..
ill list them just as they are listed on the trans

ACO 48A

330V

E 0


100V
DC20MA

230V
DC50MA

320V
DC50MA

DC0.3A

14V

on the same side as the primaries i also have a 6.3V for the heaters

i need 650v 150mA

and 180V out of this thing to run my 2 tubes as shown on my P/S schematic

no i KNOW it is capable of it since as i said it came out of a radio that ran 2 of the same tubes

how to i go about summing the voltage out of different taps to get the numbers i need??thanx for the help

It is not possible, because the amperage will not be summed if you'll connect voltage in series. You will get the lowest value - 20mA, and the 650V.

well how did they do it in the radio originally then??

the transformer came out of a kenwood T-599 that ran the same tubes as what i'd like to use

im so very confused lol

[scottericsonon]

anybody else??

as i said this trans came out of a radio that ran the same tubes......

how did they get away with running them there??

no i dont have a schematic for the original radio
