It could be something simple like a fuse - it could be a failed soldered joint on the PCB - bad component.... I have a Cube 60 schematic (circuit diagram) in front of me - there is a preamp out and ma...

Cheers @rocknroller912. I'll look at it more closely when I get some time over the next couple of days and try to spot anything obvious. If nothing obvious then I'll probably just revert to planA and...

@tv1010101 Amps usually pass a signal through different stages to get up to full power, first a pre amp then the main power part, which I'm sure you already know. It sounds like you are getting only t...

@rocknroller912 I have a Roland Cube 60 (cost me peanuts), which I was intending to cannibalise just for the cab & speaker. However - if it worked - it seems like it'd be quite a versatile thing, ...

@tv1010101 Possibly although I haven't looked at electronics for several years but I do have two clever friends who are amenable to questions. What problem do you have.

@frocesterbill Looks like you are the forum valve expert so far

I even threw out the digital amp that I built for the exam which had active bass/treble controls built into a feedback loop. Does that mean you're a bit handy with a digital amp's pcb, a schematic, ...

@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 th...

I built a valve amp 4 or 5 years ago - try a search on AX84 - there is a community based around a single ended 5 Watt amp with an EL84 power valve. There was enough detail for a novice to build an amp...

I watched the video link that you posted, the instructor really knows his stuff. It's a course I would like to do also. @rocknroller912 I’ve known Chris (Rift Amps) for a few years. His amps are pre...

@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 ...

@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 underst...

Sorry @TV1010101 it looks like you already covered that point..

I’ve been trying thinking about the bridge. You should still be ok with a set neck but the angle may be shallower than say a W/o bridge. What height is the bridge? As long as the neck angle hits at t...

I agree with @TV1010101 mahogany would be nice. Could you not do a bolt on neck but glue it in. I’ve always thought bolt ons should have a slight angle in any case and that’s why some shim them. Pers...

I meant to put in the post ...what I mean by glossy is the same paint and lacquer as one. It’s a similar process but not polished to a shine...it still needs filling (unless you want visible grain).

@tv1010101 They're all marked 500, A's and B's, so thats not a problem. The theaded parts all measure 8mm, I'm assuming that they're metric. I'll pop into my old workplace when I'm home and borrow th...

TV romping up the ratings by triple posting...... Oooops! Now deleted ... there were some website errors when I was posting that reply, so whatever I did in response to the error (F5?) obviously repe...

Trouble is @Robin, that the diameter of the threaded part varies. I've got a box of washers & nuts, but odds are that they wouldn't fit your pots. New ones generally come with more washers/nuts t...

I bought some used pots from ebay, I got into a message discussion with the guy and told him what I was doing, I think he has sent me his entire spares box. So now I've got 20 pots, but no nuts and wa...
