EZ260 Tube Amplifiers and Tube Projects. Working Relay BCD Decoder. December 3, 2015. Been a while since I posted on this subject. I have had the PCB fabricated and assembled one BCD controller. It tool a long time to solder in all the parts, but eventually it got built. After some initial testing of the PCB I found that I had messed up ONE circuit, the one […]. April 22, 2015.

EZ260 60 Watt KT88 Amplifier | EZ260
http://www.ez260.com/2013/11/13/ez260-60-watt-kt88-amplifier
EZ260 Tube Amplifiers and Tube Projects. EZ260 60 Watt KT88 Amplifier. EZ260 60 Watt KT88 Amplifier. November 13, 2013. Edcor Transformers mounted to chassis. Transformers were custom made from EDCOR Electronics, and IMO very reasonable. As a matter of fact the power transformer made it into their online catalog. The Output transformer was one of their off regular Ultra Linear version even though I didn’t use that functionality. While I’m not super technical on the topology of this amp (Much repeat...

Relay Digital Clock | EZ260
http://www.ez260.com/2015/04/10/relay-digital-clock
EZ260 Tube Amplifiers and Tube Projects. April 10, 2015. Ok, this has nothing to do with Tube audio, but I don’t have any other place that might be a good spot to put this project. So now many years later I have decided to make a digital clock with relays. I had my share of digital logic courses over the years and have forgotten most of what I had learned. With some false starts I’m back on this project. The software basically lets you enter in a truth table and it outputs the logic! Also you can find so...

Bias Buddy | EZ260
http://www.ez260.com/2013/11/13/bias-buddy
EZ260 Tube Amplifiers and Tube Projects. November 13, 2013. The Bias Buddy, 4 channels of digital volt meters for monitoring the bias voltage. The Bias Buddy came to thought much in the same way the EZLoad. Did I have a couple of DMM’s but I was about to embark on building a Quad KT88. I had seen multi-color digital voltmeter modules on eBay and they seemed to have enough range and. The meters I used had the following specs –. Dimensions:48mm x 29mm x 21mm. Measure voltage: DC 0-30.000V. That’s abo...

EZLoad : A High Power Dummy Load | EZ260
http://www.ez260.com/2013/11/13/high-power-dummy-load
EZ260 Tube Amplifiers and Tube Projects. EZLoad : A High Power Dummy Load. EZLoad : A High Power Dummy Load. November 13, 2013. The EZLoad Project is a versatile high power dummy load for testing high power audio amplifiers. I picked up some 4 ohm 200 watt resistors off of eBay for about 20 bucks. The were imports and not very expensive given they style and wattage. I had a spare 6″x10″x2″ Hammond chassis from the EZ10. Project and fit it all to that size. Amp I figured I would need to build the EZLoad.
