Pentode Posted June 16, 2011 Share Posted June 16, 2011 I mentioned in some of my 'For Sale' threads a while ago that I had something special on the way. Well this is it! A friend tipped me off about a chap called Rob Dix of [url="http://www.rdamplification.co.uk/"]R D Amplification[/url] who builds valve amps and that it might be worth my while having a chat with him. Some of you may remember me posting a piccie of his Boogie Bass 100 head which I considered but as I had the Sound City already I thought this might be a plan worth pursuing. Ladies and Gentlemen, I give you - The Boogie Bass 120 Started off as my old Sound City 120 complete with noisy preamp. Rob gutted the whole thing keeping only the chassis and transformers and built a new preamp which is much simpler than the Sound City original and delivers shedloads of tone. It's amazingly noise free even with the volume turned right up and speaking of the volume turned up, it's also fecking loud played through my BFM Omni 15 Fullrange. Does clean and dirty very nicely thank you very much! Next thing to do is build a new head box 22" wide to go with the pair of Bill Fitzmaurice Jack 15's I've got on the go (on the go read slow in my case..). A few more piccies - Photo's courtesy of another Rob - [url="http://r-harvey.co.uk/#_"]Website[/url] Cheers Grahame Quote Link to comment Share on other sites More sharing options...

Ancient Mariner Posted June 17, 2011 Share Posted June 17, 2011 6CA7 - my favourite power valve for clean warmth. Interesting routing of the heater cable and earth rail, but if it works (and it does, from your description) then that's all that matters. Traditional hand-crafted mix of board and PTP wiring looks good. Nice to have the expected voltages marked on the chassis too. Congrats on your 'new' amp.

Pentode Posted June 18, 2011 Author Share Posted June 18, 2011 Yes I prefer the 6CA7 over the EL34 which is generally used in the Sound City 120. As you say, clean and warm. While the wiring may appear unorthodox for a hand crafted valve amp, it is totally stable and virtually silent even with the volume rolled right up. Rob spent some time getting the Boogie 120 just right and clearly wasn't going let me get my grubby little hands on it until [u]he[/u] was completely happy with it. If you want something really special built to very high standards for what I consider to be a most reasonable price, I wholeheartedly recommend you give Rob a shout.

umph Posted June 18, 2011 Share Posted June 18, 2011 fair doesn't look ideal, but it if it works why knock it! Quote Link to comment Share on other sites More sharing options...
LiamPodmore Posted June 18, 2011 Share Posted June 18, 2011 I quite like the "CAUTION - POTENTIALLY LETHAL VOLTAGES" written on in permanent marker, kinda shows the handmade factor abit. I would love that amp though, just not possible for me, or needed for that matter, but who doesnt buy stuff they dont need. Liam Quote Link to comment Share on other sites More sharing options...
rodl2005 Posted June 21, 2011 Share Posted June 21, 2011 Looks good!! +1 on the 6CA7 love too. I used to have an AUS made amp that ran 6 of them. = SWEET warm CLEAN sound! Quote Link to comment Share on other sites More sharing options...

Pentode Posted June 23, 2011 Author Share Posted June 23, 2011 Glad you like it Gentlemen. Once I get around to sorting the new headbox, I'll bung some more piccies up (don't hold your breath though..). Quote Link to comment Share on other sites More sharing options...
