Well, here it is, the initial entry into my thread on building a Weber 5F6A Bassman amp kit. What have I gotten myself into !?!?!?!?
The kit arrived in two large cartons a few days before Christmas, but I was a good boy and did not open it until Christmas day.
What I found inside was amazing.
The cabinet is absolutely beautiful. It is made out of finger jointed pine boards just like Leo made them. It smells wonderful. The Weber 10" Alnico Signature speakers are already mounted. The Tweed covering is applied perfectly. I was going to lacquer the cabinet, but that would have to wait until spring. As it is, it is a perfect match for the Tweed covering on my Blues Deluxe Reissue. It looks like it was cut from the same bolt of cloth. I think I'm gonna just leave it alone.
There are no instructions included, just a parts inventory. The schematic and wiring diagram must be downloaded from the Weber website.https://taweber.powweb.com/store/5f6a_schem.jpghttps://taweber.powweb.com/store/5f6a_layout.jpg
All the parts are stuck in bags and nothing is labled. The Alpha pots have their values written on them in sometimes hidden places. I'm going to have to print out a copy of the resistor color code as it has been too long since I used it. I'm not sure who the cap manufacturers are. The eyelet boards appear to be of good quality. The transformers don't have any manufacturer names on them but they appear to be well built. The chassis with its chrome plating and lettering is very nicely done.
My intent is to build the amp as close to the original schematic as possible. I have noted a few differences in the Weber schematic compared to the original Fender one that I plan on changing to the Fender values. I also plan on adding a bias adjustment pot. I did not order tubes with the amp. Once built I plan on using some spare tubes I have (mostly the GTs that came out of my BDRI) for testing and initial operation. I then plan on switching to the 59 Bassman tube kit from Eurotubes (JJ 12AX7s and JJ 6L6GCs) with a NOS 12AY7 in V1. I have priced out a nice set of NOS tubes from KCA but the cost is more than I can justify right now. But my birthday is coming up in April.
Anyway, I will update this thread with a description and photos as work is completed. I have no idea how long this will take me or how often updates will be made. Just hang loose, subscribe to this thread, and watch for update notifications. It should be fun. Please wish me luck.
