[quote author="[silent:arts]"]HEATER PSU

the Heater PSU is a rectified, unregulated one.
the bridge rectifier should be a 12A or more, mounted off board to the chassis. they look like this:

behind the rectifier we have:

we want to be as near as possible to 6.3V, this is done by the value of R15.
again: this resistor is mounted off board and gets very hot. a 50W resistor is a good idea, something like this:

now, what value do we need ?
according to my data sheets:
6BC8 @ 6.3V = 400mA
5687 @ 6.3V = 900mA
this results in 2.6A heater consumption EACH channel.
now you can do the math :green:

one problem we have with the "right" value of R15:
- mains voltage will vary
- the secondary of each transformer will vary
- the consumption of each tube will vary

best thing is to have a few values handy to test it.[/quote]

OK guys you got me on this one.

I've been resisting the urge to ask but as this is the last piece I need to order so I'm just going to have to swallow my pride and admit I have know idea what were talking about here.

I am building the stereo version with Codered's US group buy Toroid Transformer
( Hoping I can wire this up for 240V usage we have here in Australia).

Is this something I will have to wait for others in the know to work out when the Toroid arrives in arround November or do we have enough info on this already?

 

[lewilson]

Where can I get the 5 and 7 pin terminal blocks for the power supply pc board?

 

[Moby]

Is this something I will have to wait for others in the know to work out when the Toroid arrives in arround November or do we have enough info on this already?

Well as you can read there is no rule of thumb for this resistor since voltage is not regulated. If you want to order something and you are not sure about exact current running for heaters I will advice to go with variable resistor so you can trim and purchase the resistors later.

Hell with buying a bunch of 50W Resistors.... buy yourself one of these 50W suckers and then do the test/measurements to buy the right value. You can use it with for all your future projects.....

 

[seavote]

as per the heater supply. is there a reason why an unregulated heater supply is preferred in this application? can we use a regulated supply or is it not practical in this circuit? heat an issue???
sorry if its obvious i'm teaching myself electronics. im only 2 years into this/thanks

Hell with buying a bunch of 50W Resistors.... buy yourself one of these 50W suckers and then do the test/measurements to buy the right value. You can use it with for all your future projects.....

yeah I was thinking of one of those too. as they are ceramic, they would survive in a stereo version ? or is a fixed value resistor a better solution for permanent use ?

 

[elektrovolt]

Sixtyniner, please read the partslists in the first post, and read the whole topic. no need for this spamming, so please stop it.

 

[SIXTYNINER]

HI
FIRST MY POST ARE NOT SPAM!!!
OTHER GUYS NEED SAME INFO
HERE NOBODY POST NOTHING ABOUT.

I READ IT AND READ IT AND RE-READ IT
BOM LIST PUBLISHED
1-SUPPLYERS CHANGE CODES OF PARTS
BUT IF BOM LIST INCLUDE NECESSARY INFOS (NOT AS PUBLISHED)
IS SIMPLE FIND PART REPLACEMENT

MANY ESSENTIALS TECH SPECS ARE ABSENTS
I'M NOT AN ELECTRONIC ENGINEER
BUT I WORK WITH ELECTRONICS FROM 10 YEARS

THE CIRCUIT IS TUBES,
NO POSSIBLE " TRY AND ERROR" AS IN "MIKROSOFT" MANUALS
400 VOLTS KILL PERSONS!
THEN ME AND MANY OTHERS
MUST TO BE SHURE

DO YOU UNDERSTAND OR NOT?

I think he's doing it on purpose... I just got 3 PM's from him YELLING AT ME!

WTF is it with this guy?

69er - Here's the parts list AGAIN:
http://groupdiy.silentarts.net/PM660/PSU660_rev02-PartsList.pdf

READ the thread to fill in the blanks & ask ONE question at a time to fill in what you feel is missing... SIMPLE!

Hey Volker,
Maybe it's time to update the Parts list with some of the new or updated info so some of the same questions don't swamp the thread... just a though.

 

[SIXTYNINER]

superthanks
i have it and read it !
is the same from this project "take off"...
see at resistor
where voltage about?
i read it 30 pages of this pm 660 thread
looking for further infos , before ask and re ask
about parts
but apart some good
edcor trafos,
rotary swithes ,tubes, and psu trafo
no other info
found
thanks the same
have a nice day
6tnr

 

[elektrovolt]

again about the heater resistor, I am thinking of a power rheostat. what value should I buy ? the BOM says something with 0,3 ohm to 1,5 ohm, so a 10 ohm should be ok ?


I am thinking of mounting it to the back panel, without knob and / or some kind of locking mechanism...



sixty: take a look in the black market section on this board. if you are fast, radiance still has four (yes you will need all four) switches. the power trafo and edcor audio trafo's are also in that section.

the tubes can be easily found on the internet, most other components can be found at Conrad fo instance.
