re: audio out/put trans.
good evening bandersen and everybody outthere,. just a qwick qwestion first?on this site is there way to type back & forth somthing like the i.c.q.chat?. befor I test the voltages on the 6w6 out/put, I also pulled the 1b3 flyback tube, I guess I figured may/be there would be no high voltage out/put. I did pull the horz. & vertical out/put, tubes already. I'm thinking at this point, I cut the wires too short coming out of the output xfrmr., I'll have to drill out the rivettes frome the chassis too cut the insulation around the wires too soilder new connections incase it was'nt the xfrmr's fault. I'll be back lator.

seeing eye tube
good morning everybody, I have an qwestion?, I was woundering, if I could substitute a 6e5 with the socket for a 6x6, I'm thinking there would have to be wireing changes, and probly other things like resisters and capacitor changes, but, I'm still woundering if it possible?.
thankyous dawgs |

Hi dawgs,
You have a couple options for pictures. 1. You can attach them to you posts. Scroll down when you are in the advanced editor and you'll see a Manage Attachments button. Click on that and you should get a popup window. Click on one of the Browse... buttons and locate your picture. Then, click the upload button. 2. Use the Insert Image button - you'll need a valid URL. I got this one by right-clicking on your picture and choosing 'Copy Image Location' from the popup menu. Then I pasted it into the Inset Image popup window. I hope that makes sense. |

Ok... Try this
1. Go to your profile page, select the picture that you want, expand it to full size, and right click your mouse on the picture. 2. Select copy image location, on the box that appears, and left click on it. 3. From the thread, click on "reply to thread" to open the box to type in your comments. 4. When you want to insert the image, click on the little ikon above the box that looks like a little mountain scene (5th from the right) a window will open asking for a URL. 5. Hit "control" and "v" on your computer to paste the URL that you have copied before, into the window. 6. The image link should now appear in the text of your message, and should show up as a picture when viewed. Hope this helps, jr (couldn't resist doing another one) |

back on subject
sorry, reall got off the philco t.v. subect. I've been experimating with tube replacements, on this t.v.. things do get better with tube replacements, only one tube in the tunner I can't replace. the (6x8) there is no station pick-up,. even though the local t.v. station is only about 3 or 4 blocks frome my house. vert & hoiz. locks are off the wall., can't get under control what so ever,. I have no volume control, because the original out/put xfrmr. burnt out frome voltage over load., if the the sprkr, has no out/put, and the screen is over loaded, I would guess., there is asmall place too start frome,. what I was woundering was?. can you take a out/put xfrmr with only two in/puts red & blue and make it work in the same set with red/blue/yellow inputs?

Are you sure you local TV station is broadcasting NTSC ? There are only a handful of low power NTSC broadcasts left in the country - the rest have converted to digital.
Referring to the scematic I uploaded: http://www.bobandersen.com/images/sc...o/tv390-06.JPG The old yellow wire is actually on the output side and it ties into the volume control. Perhaps for feedback ? I'm not sure about using an xfrmr without that tap. Maybe a divider with two resistors could be used |

A small trimpot (1K to 5K would do) connected from the speaker secondary of the audio output transformer to ground, the tap feeding the yellow wire connection back to the existing volume control should work. When you have the set on, twiddle the pot to get pleasing amount of feedback. If it oscillates, exchange the output transformer secondary wires hot and ground, to reverse the phasing (or if it's easier, the primary wires' connections plate and B+, but do not do both primary and secondary!).
