Title: Is it better to keep the OT secondaries away from the primaries?
Post by: catnine on March 14, 2013, 02:03:01 pm
In my build which I started all wrong there is a photo in my post " On these NFB " I have the OT secondary leads comming out and inside the chassis near the front and they cross over near the reservoir cap . The primary leads are short and come out right near the reservoir cap . I was thinking since It would be difficult to turn the OT 180 degrees then I would need to make longer primaries . So I thought since the out jacks are between the OT tubes I would run the OT secondaries to a point where there is a hole in the chassis closer to the output jacks yet it is just under the eyelet board . The eyelet board does have a fiber board under the actual eyelet board so the OT secondaries would be between the chassis and the botton fiber board. It would also involve moving the OT secondary leads which now go from the side facing the input section and wrap around the OT to the opposite side so they are near the front of the chassis knob end . If I do this they will end up shorter and they would be more under the chassis instead of long inside the chassis. It's difficult to explain in words but can be seen in the photo's in my last post. I did all this long ago but want to clean up the leads inside the amp and make it neater and hopfully better.

If it were my amp, I would braid those three secondary wires (Green, yellow and black) very tight together and run them outside the chassis and bring them up through right near the output jacks. Just my $.02

I just twisted them all the way back to where they exit the OT and shortend the leads . There is no place to run them outside without them being to close the the output tubes.

Is it better to keep the OT secondaries away from the primaries?

They're separated only by insulation inside the transformer...

And I thought you were done asking questions about this amp?

 You know what HBP's . I do appreciate all your help . What I cannot understand for the life of me is why in the hell since my questions BUG you so damn much , why you feel the need even bother to reply. Is it just a bug you have up your ass or the need to feel important or what, just a bad day ,who the hell knows.  Perhaps there are others who might be interested. 

 I am not a child by a long short . My questions are not directed to anyone , they are just questions , no one is forced to reply .

 So what if it is the SAME damn amp , is this the crime of the century . What I don't need is someone coming on here with crap like this reply . Yes I said it was my last question and things pop into my mind so I ask them so what!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.

 There are other forums out there . If I get banned I will live on .

There is a saying people who work in institutions say (particularly in prison work)  it goes like this, "If I didn't like you, then I wouldn't tease you"

I read HBP's post as a tease not a harsh criticism.

How am I supposed to take it. This is not the first time I have been reminded about this amp since I brought it up in 2009 . A thought comes to mind and then I think to myself don't post it because after enough times of having this reminder put up there for all to see I know it's going to come again.

 I even had one moderator counting my posts and posting the count.

 This is the internet. I don't know anyone here or have I met anyone here . I don't see the face or hear the voice so all I can go by are the words written yet I continued to ask and wonder what sort of comment I will get next.

 I go through the search first to see if what I am after has come up before and check things out as best I can before asking anything.

 Yes it's the same amp but it was something I was in the process of changing and did changes well before I posted a question here . I ask because I am not clear on why it worked or to show what worked for me.

 What may be funny to  some may not be to everyone. I was told I posted just for the sake of conversation , I get sick of defending myself and reading between the lines while feeling this is a forum to ask and offer help .

 There are personal messages designed to clear the air if needed . If I were to make a comment that may be taken the wrong way I would at least put a smiley in there.

 I don't like feeling guilty and feel I am having my face rubbed in it by asking a question or feeling I am the joke of the forum. If I am wrong then I am wrong so I expressed my feelings and lashed out simply because it was not the first time or by just one member.

 Yes all the leads originate inside the PT and OT but this by no means, means that where to are routed throughout an amp means to will not have an affect of some sort . I think this is a given.

 That's fine , I did thank you always for your help yet with the little rubs I can't quite figure out where you are coming from Man.
