| 300b lovers Hi @lynn_olson , The Hashimoto PT-100F power transformer that I'm going to use for drivers/input B+ and drivers/input filament. But I'm not sure if it has an electrostatic shielding between HV and LV sections. I can see some strips between high... | |
| 300b lovers Hi @lynn_olson @atmasphere I’m going to use a separate power supply (PS) box for my amp project. It is too big and too heavy for one box. I don’t want a monobloc solution, because it is an integrated amplifier. I have 2 GND. One is a power cord... | |
| 300b lovers Hi @lynn_olson @atmasphere , Thank you for useful information. Does aluminum provides any shielding? I will use an aluminum chassis. There is a beautiful picture of Blackbirds. But I don't see inter-stage transformers. Are they under the ho... | |

| 300b lovers Hi @atmasphere , The bottom end is predictable. ~8K 6sn7 (260v, 9mA) internal impedance and 70-80H transformer primary inductance gives -3db around 20Hz. Actually I measured -2.37dB at 20Hz and -3.62 at 15Hz. According to plate voltage-current c... |
