Can we please have a photo of the finished article. Well it uses the same case so the only difference is that the valves don't show. Ill do another internal shot once I have fitted the mute board. Just need to work out where to put it.  |

So I have asked James Transformers about an o core, others seem to have had a good experience with them so why not. if it can reduce some of the noise then that it will be a good investment.

Cool I've asked for a potted/shielded one, be interested to see how much they are.

Yes , £45 delivered. very reasonable I think. Just ask for potted and shielded. I need to measure it though to make sure of the spec.

Just sizing up for connections etc, have taken the dc blocke out and the toroidy is a fair bit smaller!  |

Ok so , under load the tx measures as follow
9.8 v I guess this is ok.
HT is coming out at 183v , is this ok? the spec was for 175v.
Mains is curently at 240v. sonthis might be having an effect?

That's a bit high....as was the first one I had from them. Put a 2mohm resistor on C5 (?... firebottle will confirm) That's what I did with that one. Was fine after. |

Couple of question, Is this across the C5P terminals ? or doe it need to be in series? Is 0.5 watt rating ok or do I need higher? thanks |

Oh yes it was yummy.
2.2M ohm across C5P, that is right.

Return of the blue LED Waiting for a few bits for the BB to arrive before putting it back together . To enable vinyl I put the Firebottle OTP back in. Sounds pretty good, might have to flog the BB....🤣🤣  |
