6V6/6L6 blackface champ with solid state bridge rectifier build

Looks fine except you are showing the PT's CT(0) led to the rectifier, instead of ground or led to a standby switch. I assume only an oversight in your layout draw, but thought I'd mention just in case-that won't be good..
I buy various values of all resistors near the values needed so tweaking in those areas is easy and not waiting for a new order. They are cheap so only adds a couple $'s.

 

You have not gone wrong with the CT, he is thinking it is the CT of the HV winding, it is the CT of the heater winding and you have connected it to the cathode of a cathode biased power tube to elevate the heaters and reduce heater induced hum. Your HV winding has no CT, that is why you needed the 4 diode rectifier, so no issues with placing it wrong. I am not a huge fan of using the cathode to elevate heaters, but it is often enough. I prefer to split up the PS safety bleeder resistor to give me a node 50-75v above ground, with an added cap from that node to ground, connect the heater CT there. I would ot bother changing it not, but if you have hum higher then you want, and you can fix it by running the heaters from a 6v lantern batter, try it my way.

The only change I would make is to split up the grounds and return each to the negative end of the filter cap that feeds that stage, volume and tone grounds to the ground of the preceding stage

 

Thanks Celeste for clarifying the CT issue. I was not certain, just trying to help catch some possiblity. I have only experience with simple CT based HV and never any elevated ground stuff.

 

I see that you are using the 240 volt tap on the primary of the transformer which is the standard voltage in England.If you would like to see how EU managed to make 230 volt the standard voltage inside EU without doing a thing go to http://www.coffeetime.wikidot.com/uk-eu-mains-voltage-harmonisation
I think it´s pretty funny.

Sometimes called Spade connectors, because the male looks like a shovel blade. More specifically called Faston connectors. The two most common sizes here in the US are .187 and .250

 

I have a bag from mouser, I bought some for my champs speaker : .250 FF RECPT 18-14 Tyco Terminals , part number : 571-422822 ( if you are using mouser ). Good luck on your build, everyone needs a champ

 

Check those filter caps. ARE they in reverse orientation...that is, are they positive to ground. MY eyes tell me that they are in incorrectly. I could be worng.

 

What Wally said. Electrolytics are backwards.

 

Well, not all of the electrolytics...but the filter caps are definitely in backwards. I would suggest checking that bias cap, also. The violet colored board cap seems to be oriented correctly.

 

tubescent, are you still with us? Easy mistake to make in the excitement of a first build, bud.
