justinsweber Posted August 12, 2017 Share Posted August 12, 2017 Dynaco MKIV 40watt mono-block tube amps. All new parts, pretty amazing. Iron is from Transcendar. These were begun as kits from Dynakitparts, New SS chassis and power coated cages. All hardware was replaced with black oxide for the transformers and nickel for the chassis. Power supply cap is upgraded. All transformers are new and wound to same specs as Dynaco Originals. Modern manufacturing techniques resulting in outputs that are more resistant to core saturation and have wider bandwidth. The frontend it handled by DIYtube posiden PCB with AC bal removed for simplicity. All resistors are high tolerance and coupling caps are Wimma. Sockets are Micanol nos providing exceptional grip. Amp is 2years old and is flawless. Amps were professional wired using Teflon wire and fully bench tested. Specs: Noise is 800uV 1.2V to full power. Bandwidth @ 1watt is 12hz to 38Khz. Sustained RMS is 37watts These amps are incredibly quick, wide bandwidth and bass signature that sounds larger than you’d expect for 37watts. Tubes: are JJ 12AX7, Tungsram E80CC, Japanese GZ34 (Mullard tooling), JJ 6CA7 tubes. All tubes are new, less than 100hrs on them. Justin 323-868-9722 I did these and they are incredible examples.... Love the classic looks and great sound. Happy to email pics to interested parties. Quote Link to comment Share on other sites More sharing options...

avguytx Posted August 14, 2017 Share Posted August 14, 2017 Great looking amps! If I hadn't bought/built a Dynaco VTA ST-70 earlier this year, I'd be all over these! Yeah, it sucks what Photobucket has done for all the images I've had on there for 10+ years. I hope they go under... Quote Link to comment Share on other sites More sharing options...

justinsweber Posted August 18, 2017 Author Share Posted August 18, 2017 Yes. I have some Jub bass bin clones. Building a top hat and including the new ESN500 network ALK made for it. Should be awesome. If you look on my instagram there are pics. Quote Link to comment Share on other sites More sharing options...

Schu Posted August 26, 2017 Share Posted August 26, 2017 How hard was it to build those bass bin clones for someone with your skills? Quote Link to comment Share on other sites More sharing options...
hogwylde09 Posted August 26, 2017 Share Posted August 26, 2017 Those are nice. If I didn't have 2 ST70'S, 1967 McIntosh MC75's pair. C20 preamp. And hoards of SS amps and preamps. I'd jump. GLWS. Sent from my SM-N900V using Tapatalk Quote Link to comment Share on other sites More sharing options...
