Hi all, In short I decided I wanted to tinker with something cheap and cheerful and landed on the 340af. After opening to take a look there are some leaky caps in the power supply on C27, C24, C45 & C46 Pictures of the insides...

Hi I have a trusty 72 and like to get it recapped. I'm fairly hands-on so would like to attempt it myself. I think soon after doing my 72 I might attempt an 82 as it seems to share similar 47uf 40v - qty 3 47uf 50v - qty 6 10uf 35v - qty 12 (kemet) T368?? Tantalum Does anyone know where I can...

I thought that I might share my progress on my repurposed 70's HiFi as a digital Music Streamer project as it is now beginning to gain some momentum. I have chosen to use my existing RPi3 which I had along with an Allo Digi One hat and a recently acquired 7" touch screen. After a bit of a...

So I wanted to measure the bias of my amp, I pronged the circuit as shown in the pic. Please help, it is serviced by a tech and in a month I want to bring it back to tantalums.

Hello, recently I've been rebuilding my nap110, and when I took off the transistor from the heatsinks, the insulating washer for the collector of the transistor fell off and broke apart. Now, the problem is that I want to find a suitable replacement for it and I don't know which brand or model...

I've acquired a Cyrus CDTX SE transport....and am aware of the expensive, matching PSX-R PSU. As well as being highly priced...this is overkill for my purposes, as I intend to supply ONLY the CD transport. As I understand it (bear with me here! :) )....the smart supply communicates with the...

After 12 months of elapsed time, I've finally finished my first speaker build. There's a bit of woodwork cheating and a few ideas on design that have gone into it. There's no passive crossover as I've designed the crossover using Linn's digital Exaktbox system and therefore the speaker runs...

I bought a Falcon kit years ago to build and have only just retrieved it from the cellar. I have the instructions (Falcon sent me those recently) but I have a couple of (probably very stupid) questions to ask someone who has built a pair of these in the past. I have asked Falcon via email but...

Hello all Moodscaper was created by Rob Jackson and is available from the App Store for peanuts. I made this vid and used the app for it, I can't play any instrument so it's a 'lifesaver'. Just homemade abstract pics merging/emerging from one to another. Best full screen and headphones...

Hi, If anyone has Bob Cordell's latest book, then you may be interested in the following video where he talks about his amplifier design which is a full design, in Chapter 4 of his book. The design is a "getting started" design, and has been built and tested by Bob. The video is at the...

Hi, May be of interest to those people who want to create their own small stand-alone network audio player. https://www.elektormagazine.com/news/free-back-article-audio-dac-for-raspberry-pi The article is time limited until 1st November 2019. It is a construction project - and uses the 32bit...

This project for DIYer is based on the Q20 circuit but it can give you power level greater than 50W. The top PCB is the Power Amp you get 2 off these the bottom PCB is the split psu board for the power amps, the 2 circuit boards are toys for the kid and are a FM TX low power device. Again it...

I am selling a few blank circuit board for product that will not be available ready made. This first one is based on the TQ Claymore but it has no Remote control. And it had a Mini DAC asnd MC/MM and a better pcb arrangement for ease of build each one comes with cct diagrams and a BOM. This PTH...
