We ordered a Weber 5E3 Kit as a Christmas present, and it arrived the first week of January and I finally got to build it last week.
Over all the Weber kit was good quality except for the pilot light bulb socket, it was the worst thing you can imagine, so I upgraded to an OEM Fender style, with a red glass jewel lamp.
My Kit went together without a hitch and worked as expected from the time I first turned it on. The only difference between this and the original Fender 5E3 Tweed Deluxe is the grounding, the standby switch and the 3 prong power cord, all of which are good things to upgrade.
Here is the schematic incase you want to try this your self
Before I started the Weber Kit, I built this amp from spare parts, (Heathkit power transformer, Fry’s Electronics copper clad boards, and an old record player tube sockets and pots) it sounds great, and very similar to the Weber kit, with the exception of a 60 cycle hum thanks to a less than perfect layout. I will be rebuilding in the next few weeks, and at that time I will be updating the layout to reduce the hum.
