/diy/ - Do It Yourself

This thread turned to shit. Back on track guys, lets talk about making shit happen.
We used to rent out old Legion halls and get temp liquor permits. $10 at the door and $5 pints means some pretty good cash even if only like 100 people show up,

Toronto underground metal cult reporting in. We've had two incarnations of the Hellhaus and other illegal rackets over the years. The time has come for another location to emerge. Great bands and (mostly) great people.

Doing any kind of music-related technical shit is extremely hard to make money at for one simple reason: musicians have no money.

Right now all I can do is offset my own music related expenses

The post above. X88r footswitch circuit.

If you do it right, you wont void it, These guys arent CSI crime team level inspectors.

Dude. Just practice on a broken radio or something. It's not hard

Here's my email, if you do this for me I could shoot you some cash or something.

Go on groupdiy.com They have tons of shit they're reverse engineering.

or, if you really want. I could use a PCB of the footswitch circuit of the X88r on slocloneforums.com You have to make an account to see the threads, It's in the schematic archive section

No, you cant do that.
However, your suggestion is stupid anyway, since it's clearly more visiblle tampering than removing a resistor. Just take the resistor out, and if you want your warranty just put it back. You're overengineering shit

Just working from memory, since I'm posting from my phone, but an AC-30 is simpler then a hi-octane. Instead of a function generator you can use a keyboard with a sinewave function. A scope is useful though, look around on whatever craigslist they have in krautland, you should be able to find one for cheap. "The tube store" has some videos on jewtube on how to do turretboards. They also sell 18watt marshall kits. Some schems say to use 1/4 watt resistors, but that's total bullshit. Purchase 1/2 watt resistors or even 1 watt, they're more reliable and less noisy. Bear in mind, this isn't like making a pedal or cmoy amp; you can't just follow instructions blindly, knowing what the hell is going on makes a huge difference and can keep you from hurting yourself.

Check out randall aikens website, as well as Merlin's "valve wizard" for good articles. Especially about grounding, grounding and layout are key

Most solid state (guitar) amps are just plain shittier, so are probably "noisier".

>>217640
what do you mean by crowbar?

>>217640
I'm not sure what you mean. In the "pi network" just after the rectifier there is only the two filter caps and a high wattage 400ohm resistor. I replaced it with a 4H choke and it sounds substantially better.

>>217632
My most popular mod so far has been putting the bias mod and a 4H choke in 5150s. Tightens the low end and gets rid of a bit of fizz, and thats a SS rectifier

>>215516
No not at all, it works exactly like a solid state rectifier. I put it in my friends 1974 Marshall that I had to totally overhaul. He was looking for a Celtic Frost type tone so he needed the headroom.
Did you manage to source out a nice choke yet?
I like this idea, OP. Be sure to keep us posted.

>>216635
In simple little stuff like OP's picture it shouldnt matter THAT much, but once you start adding gain stages layout becomes just as important as component quality. The difference between a great sounding amp and a noisy piece of shit entirely depends on grounding and lead dress.

I have. I made a little drop-in package with the socket from an old tube, a little heatsink and some RTV. IIRC, I didn't pay for any of it, it was all salvaged junk.

If you're looking at adapting a transformer outside of it's intended purpose, be forewarned that it will be drawing quite a bit of current and will need to be able to handle that.

Filament taps for pre/power tubes need to be taken into consideration, with a draw of around 0.3A per 12AX7 and .5A for a 6v6. The filaments are supposed to be seperate for a tube rec IIRC, and those vary anywhere from 1.5-3A

>>215196
Is that an ECC99 equivalent? How many watts do you get?

What you have there though, is probably enough stuff to make a few pedals. Old junk is great for screwing around/prototyping when you're starting out.

Those stereo pots look cool, try giving them a cleaning!

The only stuff that applies to (in general) is if you want a "vintage" sound, to use germanium diodes and transistors

>>215168
Should have said
I can't think of a way to get your B+ to the necessary 350V or so, without a proper transformer.

>>214892
That is a disgusting looking job. Here's my x88r

It really depends on what kind of music you play. I play black/thrash so I could care less about that myself. Be sure to use a choke though. You could also wire it for tube rec, and just drop in a silicon bridge rectifier and see what you like.

I'm not an expert, but I can't think of a way to get your B+ to the necessary 350V or so. What output tubes do you want?

what did you do to your monotron btw?

>>208262
An X88r only costs about $400 to make (including tubes,using primo parts) since it's just a preamp.
