New ReleaSSSes

[10thTx]

In order to keep some constructive dialogue going ...........

Can someone verify or correct the schematic drawing about the CF after the LTPI and prior to the power amp?

Please list the answer in reference to Q1, Q2 or Q3. Thanks

With respect, 10thtx

Looking at the #13 schematic that was referenced, I am thinking that perhaps the reverb insertion should be corrected as illustrated in the "blue"?

Can someone verify this being correct or offer an edit, please?

Q1 - Grid resistors are not required.

Q2 - There are no 100K resistor to ground. This would mess up the bias voltage and not required as you have two 470K in parallel to ground at the gridfs.

Q3 - Yes. the twp 470K's would look like a 235K to ground. Similar to a twin style stage.

Note - The bias can be adjusted by varying the value of the 130K resistor.

OK, thanks for the response! It is appreciated! I will correct the schematic later this evening (& repost it) after a response to the reverb question ...... & any other edits.

I think it might go on the other side of the junction, to the top of the 100R resistor?

?

I think you're right! THANKS

Unless someone states that is not correct, I will update the schematic to show the changes in the LTPI/CF and the reverb as soon as I have the time (& then repost them).

Any other questions or concerns or observations by anyone ?

If you can show your question referencing a schematic (or schematic section), that would be helpful.

Since the genie is partially out of the bottle - SSS #4. No guarantee of accuracy. Some questions may be answered by comparing both.

Wow! Awesome. Thanks so much.

Wow, the internet is a wonderful thing. I drew that one (the exact document that is posted above) after staring at a gut shot for months... It's the almost the same as #002 except that one has a vibrato circuit (which I did not draw). It's one of Henry Kaisers, the question is which one (i thought it was #001, and that #004 was the one that became the Sterling and Ceriatone). I could be wrong there.
I obviously didn't get the filters right - I'd ignore that one and focus on the #002 which is much more accurate.

This one...

That definitely has a different tube complement than the Ceriatone/Two Rock.

AFAIR Henry's #001 has the inverter / driver configuration.

It is definitely different - if we assume that the schematic I drew is #001, then #001 and #002 are very close (one extra tube in #001 for the trem). #004 is a different animal without the DC coupled cathode followers.
I had always thought that #001 was the silver chassis in the combo, and that #004 was the black chassis in the green suede head, but as I said, I could have these two reversed.

Thanks Max, that would make #001 the combo I posted, and the schematic I drew up.

Bill, AFAIK this is correct.
