Sony-CDP-315-Modifications-and-Upgrades.jpgSony CDP-315 Modifications and Upgrades3300 viewsOK, so I also got a Sony CDP-315 single disc player and decided to try modding it. This one was much harder as It had a pair of SMD opamps and replacing them with a pair of 8 pin DIP sockets wasn't easy, but I managed to do it just fine.

So, here are the mods:

1. Installed 0.15uF X2 power filter cap
2. Intsalled a pair of ferrite chokes (on on power cord and another on the line out flat cable)
3. Replaced original opamps with NE5532 and later with Burr-Brown OPA2134 (2134s do sound better).
4. Replaced electrolytic coupling caps with a pair of Jantzens 4.7uF/630V.
5. Replaced RCAs connectors with gold plated ones.

The increase in performance was great too, but nos as good as my ONKYO DX-C380 CDP. I plan on replacing all supply and decoupling caps with Rubycon ZLs to improve it further.

PeerlessSeas2way~0.jpgPeerless and Seas 2-way Towers in Zebrawood5716 viewsThe fun part about building these speakers was the crossover design with a Zobel and Baffle Step Compensation (BSC). I wanted to try a larger driver than a 6.5 inches. I am really pleased with the sound and image. Unbelievable sound for the cost. The crossover uses open air inductors and Solen capacitors. The Veneer is Zebrawood adhesive backed. I was able to match the grain on both sides and the fronts. One coat stain and finish followed by paste wax. The speakers are drying in the garage awaiting the living room. Next is a pair of open baffle 3 way with active cross using DIY chip amps.

DIY-6AS7-Tube-Headphone-Amplifier.jpg
DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier4462 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.

4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier3463 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 Amplifiers3533 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 Amplifier2914 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.
