Question
reay_d
Hello All,
I've been working on my Rowe R1-2 for some time now as a side project.
It has been a journey with almost every component needing some attention. Firstly the main power supply was rebuilt, Then all the computer, control, memory units and encoder were attended too (with a lot of hair pulling), then the scan control/record changer was adjusted. Everything is working fairly reliably as far as selection goes.
So the last piece of my puzzle (before the cabinet refurb) is getting some sweet sweet audio from her. She has a 64watt stereo amp p/n 602-02179.
I have been thought this piece to the best of my ability, changing out diodes and caps as required, but can't seem to put my finger on it. I have made considerable progress as I had no sound to start with and the mute relay was u/s. Now the last niggling problem is it keep blowing the Q1 Transistor on the left side driver board. As these Q1 transistors (MJE6041) aren't cheap or easy to come by I'm seeking some help in resolving this.
I believe I have isolated the issue to the pre-amp board, when I switched the driver boards over (left to right, right to left) the fault stays on the left side. I can't seem to find anything obviously wrong on the pre-amp. I'm happy to start changing out transistors on the pre-amp but I'm struggling to find replacements.
Sorry for the long post but I wanted to provide as much detail as possible. Any advice anyone can offer would be very much appreciated.
Thanks in advance,
Danny
