I asked these questions in a reply to an old post (Sho-Bud Compactra), but not sure that was a good move. Here they are again:
I always like to give the designer / builder the benefit of the doubt, but I have some questions about a Sho-Bud Compactra 100. I'd appreciate any responses.
1. Mr Evans did not use any grid stopper resistors on the input of either channel. I plan to install some as there appears to be a benefit and no downside. Thoughts?
2. All of the tube heaters are connected to the same PT winding, including the 6L6 regulator (cathode follower). I can see why this is potentially bad. Thoughts?
3. This amp has a 220VAC primary winding on the PT. Are other Compactras like this?
4. This thing is really heavy. Any reason why I should only preserve it in its original state? A head and speaker cab would be much more manageable, and I can position the reverb tank better.
Thanks and cheers,
Dale
Here are two of the attachments I added on the old post that may be beneficial to some. Dotted red lines show changes I plan to make.
