Re: Help diagnosing Pyle Receiver PTA66BT with burned resistors
You can always scrape a bit of the green resist off the track to get more copper area to solder to.

Re: Help diagnosing Pyle Receiver PTA66BT with burned resistors
Budm has given unfailing good advice.
It is always good practice to raise power resistors off the board. It was very common to see this in the through hole era and further back.
No need for any fancy tape though.
Resistors convert electrical energy to heat with 100% efficiency whether they are carbon or metal oxide. The area of dissipation is the most critical, if they are of the same size they should get equally hot if the same value. (Though I should look at Budm's temperature chart before saying...

Re: Help diagnosing Pyle Receiver PTA66BT with burned resistors
PS This last bit is impossible ha, ha, this is great to read.
Is the DC voltage rock solid? Does it wiggle about at all? All I can think of is some ripple getting through or some AC component - Though it has multiple stages of filtering/regulation so don't see how.Last edited by Trumpetrousers; 08-24-2020, 03:57 PM.

Re: Help diagnosing Pyle Receiver PTA66BT with burned resistors
Hi guys,
I've just joined this site. I enjoyed reading this a lot. I was so eager to do the repair myself...
I wanted to say the patience and effort given to help out the new chap was extraordinary. Medals should be awarded in some of these cases.
Well done to both of you for persevering and getting to the bottom of it.
Brilliant stuff.
Regards Martin.

Re: New Members - please post your introductions here
Hi there all, hope I'm doing this correctly...Adding a 'quick reply'?
My name is Martin and I have been an electronic engineer for over thirty years.
I specialise in audio, radio and Hi-Fi. I also have a good few years of TV repair and VCR servicing up my left sleeve. I restore vintage audio and build my own equipment. I have had time installing and servicing projection equipment and Crestron /control 4 etc..
I have a lot of other interests..so you can always ask, just in case.
