guitar amplifiers: guitar amplifier power supply believe in my transformer collection I have to find a suitable specimen.

| current. Plug it. |
As usual with this transformer no label, and no one knows what is connected where needs. Predicate: Very helpful. Any avid hobbyist
but thankfully has ever recorded with a pencil, which inputs have to expect about the tensions are.
 |
| 2 x 300V. But where? |
2 x 300V are now not something you really want to hold in your hand, then quickly put the alligator clips to the device and off you go happy search.
 |
| The "test set" |
First, the page for the tube heater. The Output voltage is found quickly.
 |
| Idle almost 8V. This looks suspiciously like two 6.3-V winding with center tap. |
Twice 6.3 V can be summarized well and rectify, then later humming at least not the heating.
Now for the anode voltage. I return from a center.
 |
| A 250V winding. On the other side is also a legally balanced. |
 |
| I think I have found the first-300V winding :-) |
The two inner windings should then combine to 500V.
 |
| At idle, it is of course a few more volts. |
And the two external 600V. Just what I need :-)
 |
| Hey, my meter is more than the 600 volts on it than are the maximum touch ;-) Well, I would not do it ^. ^ |
defect marking of course I know still do not know how much electricity can be seen from the good piece now, but judging by the weight it should be enough for my purposes it ;-)
