Hi all! So I got home yesterday and my tubes were ready and waiting for me! Unfortunately im getting nothing out of the amp. So am at a bit of a loss as to where to go now.  Here are the voltages I got a couple of weeks ago Mains 122 Standby switch 497 V1 - P1 359 V1 - P6 359 V2 - P1 350 V2 - P5 350 V3 - P1378 V3 - P6 378 V4 - P1 378 V4 - P6 378 V5 - P1 378 V5 - P6 378 V6-V9 P3 495 Today though I checked the voltages and am getting 525 across pretty much every thing except the mains which is steak at 122v B+ 525 B+2 525 B+3 525 So something is not right here. I put the valves In and got nothing. They aren’t getting war at all. And im getting no sound from it at all.. Any thoughts as to where I can start looking? Regards Phil

Hi All! My build is progressing! I found a very nice chassis and transformers. I have a couple of questions though to continue making progress. 1) My power transformer is giving Bias of 60V apparently not 50 like in the layout. Is this going to be ok? Do I need to adjust anything? And do I still Jump R67? 2) Also the transformer does not have a CT. So I need to create a faux CT with the 2x 100R resistors. How do I go about this?where to attach them to the PCB etc? 3) Finally, I noticed that the transformer has AC1 and AC2 going to the board at 3.15V, but also the lamp going to AC1 and AC2? Could I use a terminal strip and connect the lamp and transformer to it and then just run a wire from the connection to the PCB? 4) Can I leave out the LED’s? Do I need to jumper the pads or just leave them out? 5) The BOM calls for three external bias points but no mention of them in the layout. Where do they go? 6) If I wanted to add an external bias trim, can I just remove the trim pot on the board and just wire in a pot with the three wires going to where the trim pot should be? What voltage should I be looking for with this? And where? 7) What are the voltages I should be expecting and where am I looking for them? Cheers in advance Phil
