Re: What choke for Traynor YBA-1?
My tech put two screen resistors on my YBA-1a . I am assuming it kind of acts like a choke, to smooth voltages in a way allowing one to make use modern cheap tubes . There are no Screen resistors in the YBA-1a circuit .
Unless I can spring for a set of el34 Telefunkens or Mullards, there is a very real possibility of my Traynor, or any amp using mdern tubes, having a tube melt down, and taking out everything else down the line including possibly the PT( although the Traynor PT is massive and should be able to survive a nuclear catastrophe though ) so I think I will get an HT fuse installed..it just makes good sense on any amp .
Pardon me if I am misunderstanding the role of a Choke, I'm not a tech just skip that part, and everything else I wrote is good I think.
By the way, I am doing the 5F-6a thing with my Taynor. I am leaving the one .01 Fender Bassman value cap in - I forgot what they call that section- ( instead of changing it to the .02 plexi cap), and I am replacing the two 100K film resistors for two 270K Carbon comp Fender Bassman Value caps in the 'mixer'(?)
section.
I'm also looking at changing the bright cap on the treble to 3.33K Pf , i think it is -to work better with the 47K slope resistor. I'll maybe take a look at changing thr posts out-although it don't look like I got the bad 4 meg pots.
Heck, at some point I might even get a smaller vintage power tranny installed to saturate more like an old Bassman! I'm not sure if the tubes can be changed to 6L6's . Thats the cool thing about those traynors man..you can't ruin the value cause they aren't worth that much to being with.
