edited May 2017 in Made in the UK
A thread for every completed amplifier coming off the bench. Everything is built to order so nothing here is for sale, unless stated otherwise.

Starting with one of my favourites, it's a Plexi 18 2x12" with added spring reverb, complete with footswitch. This one has a MV, TMB+Presence tonestack, and is loaded with WGS Green Berets. I only took one progress pic of the chassis, so not much to see apart from those lovely Jupiter Yellows

    This is a new one, the Tweed 5TV.

    It's based on the first tweed-covered Princeton, the 5A2 model which uses a 6SL7 dual-triode in the preamp, driving a single 6V6 with a 5Y3 rectifier for 5W. Like all Tweed Princetons, it has both a Volume and Tone control, and puts out considerably more volume than the octal based Champs of the same era. I opted for an oversized cabinet compared to the original, which can be loaded with either an 8" or 10" speaker. A 12" speaker model can be specified in a larger cabinet. This particular one has the 8" WGS G8C speaker and has now gone off for magazine review.

    Your TV fronted Princeton (especially with a 12" speaker) really gets my attention; great looking amp, and I'm sure it sounds sublime.  Would spring reverb also be an option?

    Stunning inside and out and kudos for the old school signal generator and scope too.
    Maintained it for 20 years. This old guitar's had 17 new necks and 14 new bodies in its time.

    No reverb on these I'm afraid, sorry!

    I saw your amp on FB and it looked very nice indeed. 

    Just out of curiosity if you were to make a 5TV amp but with a Brownface preamp?  It'd basically be half a Brownface Deluxe.

    See Brownie 5 - http://www.riftamps.com/brownie-5.php

    Now this one can be ordered with Reverb

    These amps look lovely.
    Had a wee look on your website and you have some great videos demonstrating the amps. Any plans for a video on the brownie 5?
    Also read your FAQs and noticed this comment.
     Unfortunately PCBs suck the tone out of the amp

    Any chance you can explain this please? I don't understand how a wire can be more 'tone-full' than a conductive track.

    Yup, soon. It's on the next batch of demo videos, just need to find the time.

    Well, it's a broad comment in a marketing application, not a academic paper. That said, this subject has been covered many times on this forum and for me, the whole PCB vs Handwired thing essentially boils down to four main points:

    1. What is the quality of the PCB in question? A well designed, optimized, and quality manufactured PCB amplifier is every bit as toneful as handwired one. Many guitar amplifiers do not have these.

    2. What is the quality of the handwired amplifier? Again design, assembly, component choice, and worksmanship can affect the tone.

    3. Ghost capacitance - do you believe it makes a difference and does that then effect your perception of an amplifier's performance?

    4. Does having a handwired guitar amplifier inspire you to play more? Or conversely, does having a PCB amplifier put you off?

    I have played crap sounding handwired amplifiers, and great sounding PCB ones. In regards to the statement on my website, it specifically applies to the PCB versions of the amplifiers that I recreate, over my handwired ones.

    Hope that helps?

    Thanks for the answer.
    Firstly, looking forward to the video. ;)

    Secondly, ref. the PCB thing.
    I'm new on the forum and indeed new to looking into amplification at this level, so previous discussions on the topic have passed me by. Sorry if I'm bringing up old news.
    I have to admit I'm a Polytechnic dropout having studied for an Electronic Engineering degree 25 years ago that I failed to finish, so my understanding of the subject is neither up to date or complete! However I struggle with the idea that a properly designed PCB would affect tone negatively over a properly designed hand wired board. If the design or production quality is at fault then that is a problem with the design or production rather than PCBs as a whole. For that reason it does slightly smack of hocus pocus, though I freely admit I am not the expert.
    I think there are many good reasons to buy a well designed, quality, hand built amplifier. With the understanding I have currently, I wouldn't put PCBs being 'tone sucking' as one of them.

    I hope these comments come over as constructive as that's how they are intended. ;)

    It wouldn't, but that's not the point that I'm making. My amplifiers are marketed at the customers who are about to spend £1000-£1500ish on a 'reissue', and I'm pointing out that in those particular amplfiers the PCBs are not well designed and are of poor quality, therefore comparitively one of my handwired models for a few hundred more is not only better sounding but better value for money with the premium components that I use. I also back them up with a lifetime warranty.

    The entire 'boutique' amplifier industry only exists because the original manufacturers no longer offer a genuine quality product that is designed to last longer than a few years.

    Prehaps I should change the wording to "Unfortunately, poorly designed and manfactured PCBs suck the tone out of an amplifier" ;)

    Thank you.

    I haven't really as there's not enough of a market to warrant the R&D. I could do one as a custom build though.

    The PR18 is my best selling amplifier, an 18w BF amp loaded with a 12" speaker - think uprated Princeton Reverb.

    Jerome's PR18 looks great in Tweed. As usual, it's chock-full of premium components including Heyboer transformers, Jupiter Vintage Yellow tone caps, Switchcraft sockets and switches, CTS/Alpha pots, and a WGS G12C speaker.

    Really nice, I love to see this high standard of work and attention to detail. They look, and I'm sure sound stunning. 

    Must start saving or that Brownie 5!

    This is the PT20 - a 20w 1x12" amp based on the PR platform. It has a 50s Tweed preamp running into a cathode biased 6L6 power section, complete with onboard Reverb and Tremolo. Loaded with a WGS G12C as standard but is also available with the Alnico G12A.

    One day I will have one to replace my noisey 68 CDR. Chris @RiftAmps has given me much advice on amps and been very patient with me, despite not actually giving the man any money! One day I'll get him to build me one!

    Ricky's PR18 is finished in classic BF tolex/grille but with the transitional faceplate and cream knobs....looking classy! Loaded with Jupiter Vintage Yellow tone caps and a WGS G12C speaker, it's shipping off to Denmark :)

    Chris' Tweed 15TV (5A3) is finished in my new darker Tweed lacquer. It's stuffed full of premium components including Jupiter Vintage Yellow tone caps, Heyboer TXs, Switchcraft sockets, CTS pots, and yellow cloth wire. Unusually for Rift, this one is loaded with a Celestion Blue instead of the WGS Black and Blue.

    Tweed 30TV (5A5 Pro): The latest (and last) TV front amplifier added to my lineup, sitting alongside the 5TV and 15TV. Pushing out a soft 25w, it's best to think think of this amp as a beefed up Deluxe with a pair of 6L6s driven a huge 15" speaker. Stuffed with a WGS G15A Alnico speaker, Jupiter Red Astrons, and 3 x 6SL7 preamp valves.

    Simon's Tweed 5C (5C1 Wide Panel Champ) was ordered in my unique 2x8" configuration which retains the classic Champ attack whilst providing for a bigger soundscape. Looks and sounds like a mini-twin!

    Loaded with a pair of WGS G8C ceramics, a full set of NOS valves, and of course Jupiter Vintage Yellow tone caps.

    Dave's Tweed 15 (5E3) was ordered in standard configuration, but that doesn't mean it's lacking tone!

    Choc full of premium components inc Jupiter Vintage Yellow caps, CTS pots, Switchcraft sockets, UK made custom wound TXs, and loaded with the brilliant WGS G12Q 20w speaker. To protect the amp, Dave ordered one of my padded soft covers.

    From July 2017, all Tweed 15 models (inc 15C and 15TV) can now run 6L6s with a GZ34 rectifier if you're that way inclined, just plug and play!
