Mbolty Posted September 10, 2013 Share Posted September 10, 2013 Anyone play through one of these or work on them? I found one on craigslist for 250 as is. It needed new tube sockets and tubes. Fired it up after installing both....definitely rock and roll. Little nervous about the plate voltage of 540V! I will also be upgrading the caps to F&T and then more likely selling if anyone is interested... Link to comment Share on other sites More sharing options...
Mbolty Posted September 11, 2013 Author Share Posted September 11, 2013 Just replaced all the filter caps with F&T, installed all alpha pots with flying leads, and replaced a bunch of the dropping resistors with higher wattage resistors as a bunch were scorched! Sounds great, letting the silicon dry now. Link to comment Share on other sites More sharing options...
PunkKitty Posted September 11, 2013 Share Posted September 11, 2013 Nice! Do you build amps? Welcome to the HOC! Link to comment Share on other sites More sharing options...
Mbolty Posted September 11, 2013 Author Share Posted September 11, 2013 Thanks PunkKitty! I used to build and test amps for an amp company, but now I just build some of my own stuff for fun and do some repair for friends. Link to comment Share on other sites More sharing options...
PunkKitty Posted September 11, 2013 Share Posted September 11, 2013 Nice! One of the members here used to build amps as a hobby and built a few for some members here. He built my 5f1 kit and did great work. I've been toying with the idea of a 5e3 lately. But I've never attempted a build on my own. Link to comment Share on other sites More sharing options...
Mbolty Posted September 11, 2013 Author Share Posted September 11, 2013 5e3 would be a good way to learn and sounds awesome! Link to comment Share on other sites More sharing options...
Steiner Posted September 11, 2013 Share Posted September 11, 2013 That is Stellar. I'd be lucky to organize the components in the time you took to complete the job. Nice work! Link to comment Share on other sites More sharing options...
Mbolty Posted September 11, 2013 Author Share Posted September 11, 2013 Steiner thanks! It took some time, but regardless of time working on it is all the fun Link to comment Share on other sites More sharing options...
H Posted September 11, 2013 Share Posted September 11, 2013 Nice job! Got any pics of your other work? Who were you building amps for previously? Link to comment Share on other sites More sharing options...
cobrafast1 Posted September 11, 2013 Share Posted September 11, 2013 I had a Sovtek MIG 50 for many years. Loved it, but it had no reverb. I used an external reverb with it. Nice amp. Real work horse and lots of power. Sold it years ago, but still have fond memories of it. I owned it for about 10 years. Never had a single problem with it.

Mbolty Posted September 11, 2013 Author Share Posted September 11, 2013 Cobra, Yeah these amps can be hit or miss. The pots are really cheap and the one I bought volume II did not work at all so I ended up replacing them all. Really like the sound of the amp a lot. H, I used to build amps for Matchless for about three years, was great experience and a lot of fun...but ended moving up to the bay area for work. I have some pics of one amp I built somewhere...its a frankenamp right now. Input is parallel 12ax7 driving a big muff tone control and volume, then into an EF86. The phase inverter is a 12ax7 paralleled cathodyne driving 2x6v6s in push-pull, that are cathode biased (that is a mouth full). Almost sounds like a mini Hiwatt-blackface fender. I already want to change it though and try some new circuits. Link to comment Share on other sites More sharing options...
y2kc Posted September 11, 2013 Share Posted September 11, 2013 I had a Mig 50 until about 6 months ago. I sold it for more than twice what I paid for it. I ordered it new right when they hit the market and enjoyed it quite a bit. They have killer raw quality that will rip the roof off most small venues. I had no more use for it with that much power and now a great band from southern Illinois is using it on a regular basis. The pots and switches are very low quality and I had them changed right away. These are killer amps. y2kc Link to comment Share on other sites More sharing options...

I built a Vibrolux Reverb earlier this year H has been kind enough to grace us with the vicarious amp build thread; twice. The only prerequisite is that you have a tea mug with either the HOC PSP logo or tour amp's logo. Link to comment Share on other sites More sharing options...
Mbolty Posted September 12, 2013 Author Share Posted September 12, 2013 Sorry to nerd out there, I blacked out. Vibrolux reverb is a serious build, that's awesome. Any gut shots? Link to comment Share on other sites More sharing options...
bolero Posted September 12, 2013 Share Posted September 12, 2013 I remember hearing those sovtek's are very similar to a 50w marshall circuit....is it true? if so, which 50w marshall circuit cheers Link to comment Share on other sites More sharing options...

Nerd out all you like, you'll have an audience here when you do Here's a gut shot of it 95% built: I'll try to find a link to the build thread for you.
