wil 0 Report post Posted June 5, 2004 ok im pissed. i ignorantly changed the tubes in my cayin ha-1a and apparently they were the wrong ones. i turned on the power and i saw smoke coming out and the smell of burnt plastic. i squeeked like a girl and immediately turned off the power. removing the cover, i discovered that a single transistor on the PCB board was burnt. Qns1: Is it still safe to run the cayin without it catching fire and burning the sh!t out of me while i listen to my music ( if yes, proceed to qns 2 ) Qns 2: Is it still safe for me to tube roll the cayin without it catching fire and burning the sh!t out of me while i listen to my music ( if yes, thank you very much for your help! ) HELPPPPPPPPPP Share this post Link to post Share on other sites
peekarwe 0 Report post Posted June 6, 2004 gulp. I am new to the business but may I dare try to provide another perspective. When you said wrong tubes, did you mean wrong specifications? Do tubes have polarity? Share this post Link to post Share on other sites

wil 0 Report post Posted June 6, 2004 Btw, i dont think its the power supply.......cos it still powers up perfectly now. Its just the transistor that im worried about. Btw, what is a burnt transistor indicative of? Share this post Link to post Share on other sites

hacknet 0 Report post Posted June 6, 2004 ahh.... burn resistor. my guess that the tube was off speced. its probably a plate resistor. since resistors don`t short across, it safe to turn on but i don`t advice you to. its a simple repair job. should cost too much. i`d be happy to take a look.

jtfoo 0 Report post Posted June 6, 2004 (edited) lol...why so ? Come to tube stuff, Frankie is a nice fellow. But bring in amp base on sand, it was a different story. But recent times he seem to have changed for the better. Had a rather pleasant experience when I told him I'm doing a sand project.
