![]() Then I pulled the wire as straight as possible and around the next turret. The technique I found that worked for me was to wrap almost all the way around the first turret. At first, when I laced a turret it would seem taut, but then when I pushed the wire down it would loosen up. The trickiest part of lacing the turrets (for me) was getting the wire to stay taut. I didn't really expect any, but I thought just maybe one of the wraps wouldn't be tight enough or something. I checked continuity on all the connections and there are no issues. Of course, you can't really tell that they aren't level when viewing from above. In reality they are sort of straight and not level at all. I had in my mind that the laces would be perfectly straight and perfectly level. Not really hard, but a little frustrating. So far, this has been the most difficult task. ![]() I laced together the various turrets, and busses last night. I used the drill bits I had in my garage (Dewalt) and an electric hand drill (Ryobi).īecause my board includes holes that will not contain turrets I decided to mark the holes to make it easier when installing the turrets. After enlarging the standoff holes I placed the board in my chassis and used it as a guide for drilling holes in the chassis. It took about 2 seconds with a hand drill. For some reason I thought the board material was going to be much more difficult to drill through, but it was very easy. One thing I discovered is that the holes I included for the standoffs were too small so I had to enlarge them. In the end, I still forgot two holes, but they were for the standoffs so no big deal. I then entered my holes, and printed out the board I designed and re-checked that I had all the holes I intended. I did follow Doug's instructions and printed out the scale turret board template. I used the Turret Board Design Program to make my own board. In the end, I decided to go with Mallory 150 capacitors instead but regardless, I decided to adjust the spacing on the Hoffman board to fit the larger parts I was using. I have a bunch of the blue molded capacitors originally used in Fender amps but the leads are of varying length so I'm not sure I could get them to easily fit. The second problem is board was designed for different size parts than those that I wanted to use. This is because the Bandmaster does not have reverb. The first problem is the two channel Hoffman board is too wide to fit in the Bandmaster. After doing some more reading I decided that I would use Doug's layout or at least something similar. This reminded me that I bought some turrets and a staking tool from Doug around 10 years ago, but never actually used them. ![]() This lead me to another site that sold Hoffman AB763 boards. While researching the best way to restore this amp, I came across some sites that sold replacement eyelet boards as well as boards with turrets. I figured it was time to bring this thing back to life. While cleaning out the basement I came across the old bandmaster. All of these amps were built using tags strips. I designed my own SE6V6 amp as well as a preamp. I have built a number of single ended 2A3, and 300B amps. Years later, I started building audio amplifiers. I lost interest and it went into the basement. In the end, I ended up with an amp that I could only play while standing on a rubber mat without getting shocked. I tried to modify the amp so that it would use E元4 tubes, have a master volume, an extra gain stage and a "brown sound" tone stack (whatever that means). I won't name any names because when I do people generally have negative reactions. I immediately realized that I didn't know what I was doing so instead of giving up, I bought some "mod kits" from a dealer that is still in business today. I read an article in Guitar Player magazine about someone modifying an old Fender and thought I would try. I had never done any electronics before and probably should never have even tried, but I was young and stupid. I originally bought my bandmaster head around 1992. I shared some of this information in other posts, but since I have started my build I thought it might be helpful to people in the future to keep a log of my project.
