PDC400s.JPG$50 Teac PDC400, as good as a $700 NAD C5423554 viewsOf course in its day this five CD player with four times oversampling and dual DACs would have cost a lot more than $50. But from a secondhand store, in a sleepy fishing village in southern Australia, this was a real steal! It has removable cover and hinges. No remote. And it works 100% flawlessly and is in excellent condition. Seen here with my headphone driver and ATH-AD700 headphones. I obtained two identical CDs and identical cables and put both the NAD and Teac through an A/B switch.Queued both CDs perfectly and switched from NAD to Teac repeatedly to try to resolve which played better. There was absolutely nothing between the two. The Teac performed as well as the NAD in every area. I have been told that if Teac went to the trouble of installing dual DACs it would definitely be a good player. I have about thirty hours of play on it in a very short time and it delivers clear and detailed music and works very well with my 2N3055 based headphone driver. Yes, a real steal!

Picture_024.jpg1930s style singled-ended pentode4487 viewsThis is a new amplifier I designed and built using mostly salvaged parts from British electronics of the 1930s and 40s. The valves are all British 4V types, AC/SP3 driver and N41 pentode output. The power supply uses an MU14 rectifier. The loudspeaker is a 1930s energized type - so it also acts as a smoothing filter.
See http://mike.wepoco.com/retro-geekery/wireless-world/1936-monodial-ac-super/monodial-psu for more information.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier6687 viewsMy name is Laurie. I have been building and DIYing for 45 years now and happily will never stop. This tube headphone amp is from a thread in the Form.
The power connecting cable comes from a European Travel Iron I bought for $1.00 at junk shop. (220v/6A) They will be shortened when I find a perch for the amp and me. The sound is better than my ears have ever heard so I will be keeping this one for my retirement entertainment should such a time ever come. Wink It has worked from day one and continues to please me every time it is turned on. The tubes are JJ ECC88 / 6AS7 with a 5V4 rectifier tube. To spite it's small size the parts are quite easily accessed. I over built most components so it will outlast me I fear. The only change I anticipate may be the 6AS7 to a bottle neck glass to match the rectifier tube. I do have and use a 6080 tube, but i can tell no difference in sound. It will take more then a few hours of listening to get my ears better tuned.Feb 28, 2017

4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier5329 viewsThis 4-channel 400 W amplifier uses Hypex UcD400HG modules together with the corresponding power supply.
The whole is mounted inside a Galaxy 330 x 230 x 80 case.
For building instructions, have a look at this project's wiki.
Two such amplifiers has been working for over 2 years in my lounge, driving Linn Komponent 110 loudspeakers which each have 4 speaker inputs.

E88CC-SV83-SET-Amplifiers.jpgDual SV83 SET Amplifiers5499 viewsA mirrored pair of SET amplifiers, presently being used in bridged mode. All P2P construction using silver solder. I included a "Hazen grid" capacitor and input tube bias change switch. The single mA meter displays individual output tube bias current with a Left/Right switch. Edcor XPRW178 power transformer and GXSE10-6-8K output transformers. Upgraded caps to Jantzen Audio 1200V Z-Superior. Upgraded resistors to PRP PR9372 Audio for metal film and TAKMAN REX for carbon film. ALPS Blue 100K attenuator. The power supply uses a RCA 5U4GB rectifier and Hammond 156R choke. Matched pairs of Svetlana SV83 for power and JJ E88CC for the input tube.

6V6-Push-Pull-Amplifier.jpgPush-Pull (PP) 6V6GT Tube Amplifier4528 viewsThis 6V6 amp was built following the DIY Push-Pull (PP) 6V6 / 6V6GT Tube Amplifier Schematic. Power Supply transformer and Output transformers are handmade in Argentina by NavasBaccino. I'd like to thank Brad S. for the help. The sound is amazing and clear, free of distortion.
