I had the chance recently to pull one of those PA bins outta the trash as my regular venue, fix it up and hand it on. After looking at the power supply, chipset and speakers I thought they'd be selling for about 300 bucks and I was really surprised when I found they were selling for 1.5k....! It was...

I've been working on my own tube reverb lately and while doing so I opened up the tank and played it with my fingertips....way loud!!! So the problem is always one of getting enough drive... and most of that want's to be current. We look at cathode, emitter and source followers as somewhat useless b...

Most transistors don't mind what they're called and it's quite simple to replace something with something very common. You just gotta identify the basic parameters and realise the job they have to do.

Such is life. We stand on the shoulders of Giants. Ownership seems to be what makes is difficult. New ideas take time to break into the paradigm that exists... but as soon as they break the mold...everybody wants to clone... maybe so they can store enough nuts to take the time to be original. Everyb...

Sorry about the taking away the title block... even though I didn't. That was how I found it. It's a straight copy and paste. I suppose thats the thing with the internet. Most things come from the application notes... but once they get on the net they go round and round and back through themselves m...

This is something I've had on my bench for a while now and want to get back into finishing. Basically the signal goes to some LM386's then drives the speakers with the cones removed and the tongues added and this drives the springs. At the other end the plastic spring is wrapped with guitar string, ...

I made the knobs a few years ago, my first run of carved resin that was taken to the foundry and cast in pewter... but it's such a hassle drilling them and tapping them that the idea of creating knobs for musical instruments just became a little too time consuming. But I'm thinking about doing it ag...

Haha, funny you should mention steampunk. I had no idea what steampunk was till a few days ago when someone from America went to a gallery I have some work in and they mentioned steampunk to the owner, he told me about it and the other day I found out all about it. It's kinda funny as well that I us...

New Zealand again, I most probably know the other guy even :lol: Anyways just joined, built something using a planar ribbon, in the course of playing with carbon capsules, basiclly just playing with all the assorted little pressure pickups I have lying about.. Good golly, I could go on for hours... ...

First post, and I'd forgotten about tape op but I do have one issue of the mag, the one with Mr Royers article about making the tube mic, and I have the Tape op book which I remember every so often and have a read of. Reasons for the above, I live in New Zealand and thats kind of a long way from eve...
