codhead Posted August 20, 2005 Share Posted August 20, 2005 Here's Rev. 2 of the amp I purchased from Amplitube, FedEx having destroyed the first. It's a new ST-70, built on Scott's late-model Dynaco replacement chassis - and it's a real beauty. The amp is all new construction, and is built with almost all American made parts. Keep this in mind if you're contemplating an inexpensive new tube amp. Made here, assembled here, and new amp reliability - for around 600 bucks. Why go Chinese? It really does an outstanding job driving my '76 Heresys. As much as I like the Moth s2A3 I normally run in the bedroom, I have to admit that the little Dynaco has some conjones if you push it beyond 2A3 listening levels. While the mids may not be as refined as the little SET, it certainly has a way with classic rock that makes it a joy to listen to. Quote Link to comment Share on other sites More sharing options...

jt1stcav Posted August 20, 2005 Share Posted August 20, 2005 An American classic, and a thing of beauty, too...not only the chassis and updated build, but the powerful sound of EL34s as well. Must've missed the original thread, so bear with me on the questions...who actually rebuilt this particular ST-70, and from NOS parts or parts from an existing amp? Whoever did this remarkable update on this venerable Dynaco sure knows his way around this amp's design/construction. Enjoy your "new" ST-70!

He does business under the name "Amplitube". It's all newly manufactured parts. The first one had original Dynaco output transformers. After FedEx dropped it, he built me another one from scratch - everything is new on this one. You can do a search on FedEx for my previous thread where the last one got damaged. Here is the original eBay listing, if you want to read about his amps. If anyone wants to contact Chris about an amp, his E-mail is amplitube@sti.net (he also sells these as kits).

I remember the ad saying that the black chassis - like your amp - was an upgraded part over the earlier chrome model. Apparently the chrome chassis was pretty thin (like the original ST-70) and was easily damaged in shipping. Looks like you got the good one.

He bought a load of my first "replica" attempts that have kind of a flat nickel plate finish. Codhead's was made from a chassis I made a couple of months ago. They both look great, just different. Dang that ST70 chassis does look great if I do say so myself. Really, the whole amp looks fantastic. Scott Quote Link to comment Share on other sites More sharing options...
jt1stcav Posted August 21, 2005 Share Posted August 21, 2005 Scott, you do fantastic work (you should be proud)! When I'm in the market for a more powerful tube amp that's NOT from Hong Kong, I'm going to look Chris Miller up on eBay. You just can't beat a proven design, and it seems to me these NEW Dynaco ST-70s are even better than the originals (being built in CA is a definate plus, too)!
