“This is my Tweed WF-55 Champ with a new extension cab. The amp is modded with a NFB switch, r6 boost and a 6L6 tube with slightly hotter bias. It sounds great and even better with the 12 inch extension cab. The cab is covered in fake leather and loaded with a WGS et90 speaker. […]

As well as adding a full tone stack, Grahame added the VVR (now called VCB) circuit to allow full distortion at lower room volume. As you can see it’s quite tightly packed. “The wood is meranti, an Asian mahogany, stained and then sealed with poly and top coated with acrylic urethane. (Same process as PRS

“All finished now and testing today. Sounds really good and warm even without the Celestion Gold 10 having worn in yet. Tried a number of guitars through it and all sound good with nice tonal variations. Attaching some pics of the combo in build.”

“Just finished the 4watt tweed sounds great. I like the Tung-Sol 6v6 but they all sound good; just think the Tung-Sol has a creamy blues sound and using a 8in WGS ceramic speaker helps.”

“Kit arrived yesterday, everything is perfect and I’ve managed to get all the hardware mounted into the donor chassis. Because of the way I had to fit everything in, the input jack is quite far away from V1, so I had to add a wire running from the socket to the valve as well as

“The covering is black leatherette of the sort used for upholstery and occasionally fashion clothing and has a sort of white cloth back. I stuck it with PVA glue. The little amp corners came from Etsy which is a most unlikely supplier for such things. They normally supply a lot of craft type stuff. The

“I have just completed the WF-55 kit. This was my first go at assembling a valve amp and a few awkward moments aside it was great fun. To my great surprise the assembled amp powered up and worked like a dream first time. I had the fire extinguisher standing by just incase! I’’m no expert

“My completed amplifier is now, and has been up and running for some time: the sound is great through a Celestion 8-inch speaker (nice and tight for the volumes I use it at). “The amplifier is enclosed in the custom cabinet from Chris: I opted for the additional ventilation grill fitted for an additional £10.

“The WF-55 I made this year is performing brilliantly and has been completely problem free. Here it is in the head I made for it. The cab has a 12-inch Celestion blue. All made from old pine shelving, cheap sofa cover leatherette and a chrome tile edging strip for trim. “The Celestion blue is really

“Just wanted to say a huge thank you for all of your help during the build and tweaking stage of the WF-55; the build guide was incredibly easy to follow! Modifications I made were to add a Fender bright switch, an all-boost switch and a rotary switch for speaker impedance. I also changed the circuit

“This makes an impressive noise through this old Danelectro speaker. It’s currently running with no negative feedback but I’ll be installing a switch soon so I have both options.”

“I thought you would be interested in this post on the BYOC forum about my WF-55 build: (link gone!) “I’m sure I will build another amp. Thanks for producing such a great product and for all of your support.”

“I completed my WF-55 amplifier and it sounds great. It’s one of the most enjoyable things I’ve ever done. Thank you. I’ve attached a few photos as I thought you might be interested. “Mods from the standard were to move the power switch to the front for access, adding a Fender-style jewel light, adding an

“You may remember a while back I bought one of your plain cabs for the WF-55 amp. Here’s a couple of pics of the finished article, covered in vinyl ‘Tolex’ and lined inside with self adhesive foil to help with screening. It presented a bit of a ‘learning curve’ as they say as it was

“This has been my first start to finish amp build and as I intend to use the amp with a bass I made a few changes from the start. The preamp is as per your design but with a GT 5751 and a 22uF cap on the cathode of the first gain stage. I also

“I just wanted to get back to you with some feedback now I’ve been living with my WF-55 for a couple of months. Firstly let me say that the build was a piece of cake due to your outstanding instructions – worked beautifully first time. It was quite a thrill plugging the speaker and then

“Just a note to say thanks for the kit. It was all too easy, your instructions were most excellent. Have attached a couple of happy snaps of the amp in its Tasmanian Blackwood cab. “I ended up using a Jensen P8R, as it was the only 8in alnico I could source locally. It sounds good,

“Here are some photos of my WF-55, now that I’ve finished the cabinet, and tweaked the amp a little. The cabinet matches my boutique 18-watt amp, so I also have a 1×12 speaker cab that will match the WF-55 if I want a fuller sound than the 10-inch Jensen I’ve paired with the new amp.

“Sweet Tweed. With mute, tone control, negative feedback defeat and cathode bypass caps (22uF/none and .68uF on V1).”

Peter wanted a WF-55 combo, but with the valves pointing down instead of forwards. So he did a bit of metalwork, as shown here.”What a beautiful amp. The tone is lovely and it is virtually noiseless. As promised I have attached some photos to show how I built it, using the supplied chassis, so that
