WF-55

“Hi Barry. Hope all is good with you in these strange times. Ages ago I sent you a photo of my WF-55 amp. I then made a speaker cab covered in a matching tweed material. To finish the job I have now made a ‘Tweedocaster’.

“Here is a picture of the finished WF-55 housed in a recycled Park practice amp box and using the Park/Marshal speaker. I might tidy the front end up later with a new front panel.”

“I built a WF-55 kit some years ago. Finally it’s completely finished, in a combo which I built with a friend of mine. The speaker is a 10″ Jensen Ceramic C10Q, and the amp has some mods like fat switch, VVR, impedance selector.”

“Finally I have got the WF-55 ready to go. Here are some pics. You maybe better put your sunglasses on before looking at the pics. The colour may damage your eyes ;-) It’s seafoam-green tolex. I was inspired by a customer’s seafoam-green Strat-style guitar. “For the panels I had the idea of using a piece

“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.

“Thought you might like to see a couple of pics of my finished WF-55. What an amazing sounding amp and so easy to build with your instructions! I’ve built mine as a combo with a 10in Celestion Greenback inside. The combo is the bare minimum width to fit the chassis, held in place with Allen

“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

“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.”

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

“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

“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.”

“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.”

“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,

“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.”

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

“Thank you for your help building my WF-55 project. Some of my friends are now interested so I will point them in your direction. “The cabinets – obviously tweed covering finished in nitrocellulose with leather handles, metal slider feet on speaker cabinet and rubber feet on amp, and an 8-inch Ted Weber signature speaker. The

“Wanted to show you some pics of my build. Cab is cherry wood veneer over MDF board with solid cherry trim. Vintage style cloth front, similar to an old radio. NOS tubes.   “The piece underneath is an Epi Valve Jr. head converted to a reverb unit, speaker cab I also built, royal blue tolex

“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

“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

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
