@tv1010101 My knowledge of valve amps is limited but I do know they have a heater and a bias voltage which makes current flow. Large value capacitors are used to store energy and act as a buffer (I think) between…   Read more»

@robin Nuts and washers shouldn’t be too hard to find. If you have calipers measure the diameter of the threaded bit on the pot. Exact metric measurements have a standard pitch size (distance between the threads) eg 10mm might be…   Read more»

@tv1010101 I watched the video link that you posted, the instructor really knows his stuff. It’s a course I would like to do also. Looking at the photo of the kit which you are intending to build, do the capacitors…   Read more»

@darrenking I take your point about experts completely, think that’s how people become experts by debating everything to infinity. After watching the video posted by @tv1010101 I now have more understanding of the way valve amps are put together, as…   Read more»

Ive just checked the link you posted for Vyse Amps and see that their photos are all hard wired components not pcbs so I think this points me in the direction I need to go. Thanks very much.

@tv1010101 The circuit diagram for the connections isn’t that hard but my friend suggested putting the resistors/capacitors into a printed circuit board which can be tricky to design and make. Another friend who is qualified in electronics says this is…   Read more»

Think I would like an amp building course do you know if any one has contact details for Barry Vyse. 

@tv1010101 My friend bought all the individual components for the amp and designed the circuit himself. The base is flat aluminium folded on a machine. He does have a degree in instrumentation so it probably wasn’t too hard for him…   Read more»

Love all the drummer jokes. I used to have a boss at work whose favourite story was to boast about the time he sat in with John Mayalls Blues Breakers at a gig in Carlisle as the regular drummer took…   Read more»
