Geloso G209 caps unknown.

[carlos10]

hi,
wonder if someone can tell me the value of the caps marked wit blue arrow,
they are covered by other printings
wiring schemtic atached

[DMcMahon]

I can hardly see the blue markings let alone read the capacitor values, maybe a good photo of the capacitors would help.

Have now found more readable documentation for the G209.

For the 2 blue marked capacitors at the 6AQ5 (V12) valve, pin 5 (anode) = .01 (so assume 0.01uF), pin 7 (Control Grid internally connected to pin 1) = 100uuF (connected down to ground) so believe this will be 100pF. Capacitor voltage ratings/type not listed.

I think you show a third blue marked capacitor below the other 2, still to work this one out.

thanks to all who reply, the pic has bin resized by the forum here i think,
all the caps are for the 6aq5 and around,
there was an atempt to replace the 6aq5 by el84 but never finished, a lot of wires hanging loose or removed, so i choose to install a 6aq5 back ,
lots of info and a nice wiring diagram , but some values are overprinted,
thanks to david for the info sofar.

Hi Carlos,

There is a full manual for the G209 at BAMA Archive, and although it is in
Italian, there is an excellent schematic with all values marked.

Kind regards

There also is a manul at electrotanya (Italian and English for the main text).

I am struggling with the third blue marked capacitor, the component layout drawing is very difficult to follow for this component. It looks like it connects to the bottom of the 0.01uF capacitor, but on the schematic there appears to be no capacitor connected there, although there are several resistors connected to this point. Can you confirm the third blue marked component is actually a capacitor, on the component layout drawing it possibly looks like it ends with a k so maybe a resistor, a photo would help to clarify.

The 0.01uF capacitor is across the primary of the output transformer so ideally needs to be AC voltage rated or a good (high) DC voltage rated.

I'm looking at a manual downloaded from the BAMA site and also Elektrotanya, I can't see any components marked blue or any blue arrows....Only wires labeled Bleu

Marked up blue (arrows ?) in Post # 1.

David

[carlos10]

No, that's because I set the arrows there in blue.

I think they're resistors ,there is a 5 pole connection board beside the trafo, one resistor connects from the anode pin5 to the first connection pole on the board, there is a second also connected to the first pole and then connected to the number 5 pole on that board, the first resistor with nero on it (black) should be 1k I think

[DMcMahon]

Yes you added (marked up) the blue arrows to point to the capacitors in question.

David

[ms660]

I can only just make them out if I tilt my PC screen back....There's four components with five arrows is that correct? They're not very well defined on my PC screen at all.

yes the component under has 2 arrows pointing, there should be resistors i think

Very difficult to be sure, I thought 3 arrows (1 each) for 3 components.

So how many capacitors were you asking about, just the 2 that have been covered ?

The one in question for me is the component where its bottom end connects through to terminal 1 of the loudspeaker out connector, which I think is a resistor, were you asking about that component ?

David

[carlos10]

david, you have stated the 2 capacitors on the 6aq5,
the small one with the 100 printing(i think) is connected fron pin 7 to to the 6aq5 midle grounding tap,
the second 350v cap is connected from pin 6 6aq5 to the grounding lug of the 7 pins small connection board on the right from the 6aq5,
the other are resistors for sure, they are connected to the small 5 pins connection board to the right oft the trafo 321/2,5 mark on it, one resistor has nero written over it, the other marked with to blue arrows has the black wiring over it , so not readable

[DMcMahon]

Carlos, just to be clear, do you need help with any of these resistor values ?

David

[carlos10]

yes, if possible
i cant read the value on it because its cocered by other printings,
i have here a far better copy of the wiring diagram
the quality of the the copy i atached is bad if you zoom in
its not possible to send a better copy due the restrictions of the forum

This does not look correct ? the second capacitor I followed goes from anode pin 5, pin 6 has a 2.2k resistor and 8uF connected to it.
