Bucket Head Posted March 14, 2015 Share Posted March 14, 2015 hi guys, hope its OK to post this here. Bought this a week ago at a car boot. thought it looked interesting and was possibly some kind of Valve testing jig. I've been looking into doing valve replacement and amp repair and thought it might come in useful if it was (and it was only a 5er). Anyway I've been looking all over trying to find out what it is and no luck! was hoping one of you guys might know something about it. cheers BH [url="http://s895.photobucket.com/user/BucketHead1980/media/20150314_120854.jpg.html"][/url] [url="http://s895.photobucket.com/user/BucketHead1980/media/20150314_121004.jpg.html"][/url] [url="http://s895.photobucket.com/user/BucketHead1980/media/20150314_120905.jpg.html"][/url] Quote Link to comment Share on other sites More sharing options...
planer Posted March 14, 2015 Share Posted March 14, 2015 I would suggest that looks like a kit-built valve amp, sans valves. Sorry, I can't be more help though. Looks like a good find for a boot sale :-) Quote Link to comment Share on other sites More sharing options...

Bucket Head Posted March 14, 2015 Author Share Posted March 14, 2015 ahhhh ok cool. so i guess that the 3 valve slots would be for a rectifier, preamp and power? Quote Link to comment Share on other sites More sharing options...
3below Posted March 14, 2015 Share Posted March 14, 2015 (edited) Looks like an amplifier to me, some pretty substantial transformers in it. Very well built, very tidy. The price was right a good buy, buy of the year in fact. Need to get a multimeter and start probing - what HT (B+) voltages is it set up for. With that info we can work out what valves it will work with. Nice project. Edited March 14, 2015 by 3below Quote Link to comment Share on other sites More sharing options...
gelfin Posted March 14, 2015 Share Posted March 14, 2015 Looks like a mono Hi Fi power amp. RCA phono input socket and standard speaker binding posts. No volume control. Post the pics on a Hi Fi forum. Quote Link to comment Share on other sites More sharing options...
Dad3353 Posted March 14, 2015 Share Posted March 14, 2015 Could it be an RF amp, for driving a radio transmitter aerial..? Short wave, or similar..? Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted March 15, 2015 Share Posted March 15, 2015 (edited) [quote name='Dad3353' timestamp='1426377446' post='2717548'] Could it be an RF amp, for driving a radio transmitter aerial..? Short wave, or similar..? [/quote] If it's an RF amp, I wouldn't be in too much of a hurry to fire it up and start poking around - RF burns can be pretty nasty.

bartelby Posted March 15, 2015 Share Posted March 15, 2015 There's about £100 worth of Mundorf capacitors in there. I've seen that layout of mono block before, but can't remember where. Quote Link to comment Share on other sites More sharing options...
