I have the standard serie and i used it for 2 years. Interstage trafo, 5k prim. I’m afraid to say it even beats my B integrated by a small margin in overall dynamics and an almost palpable midrange that reaches out into my listening room. Obviously, negative pole from the battery to grid. All of the used spray paints dries very fast, which is important as I do it outside and have to keep fingers crossed that no bugs or any wind born garden debris passes by until it’s safe to take inside.

DIY tube preamp SRPP ECC88 E88CC 6N2P 6N6P | eBay
I’m not sure about the rationale behind this capacitor, but removing it is an obvious option. Cloning the TRAM isn’t particularly difficult having the amp and assembly instruction at hand. Learn More – opens in a new window or tab International postage and import charges paid to Pitney Bowes Inc. So, with the capacitor removed and a 1.
This was the last time. No need to say more but this: Next the front panels have been veneered and are ready for drilling, routing, lacquer, etc. The 1N is a protection device for the 6BX7 and it falls out of the circuit under normal operation. Removing the mains transformer helped a lot and it didn’t need being meters away. Jan 14, at 4: Back to home page Return to top.
Adding a large sheet of aluminium between the mains trafo and left channel output trafo reduce hum, so maybe I made a bad cabinet layout after all. A very long journey into making a line stage amplifier.
I could also make things super simple by using a ‘ring of two’. Have tried adding caps right on tube pins – didn’t help.
Here the combined schematics.
6n6p operating point?
Almost ready for first time turn-on! New other see details: I plan on reading the rest of your website soon. Read 6b6p other wot line stage projects found on the web. Kiwame resistors and Obbligato film caps used in most places.
The Tube CAD Journal:SRPP vs. White Cathode Follower
This places the turnover at around Hz, which is where I usually place it. Are we done with the SRPP? Expect to see a few e-mails and new articles on this circuit. Seller information marmik18 This capacitor is basically a bypass capacitor. They do come in 3V so only two in series.
Preloading means adding a fixed resistor to the output a value slightly higher than optimal, so that when an external high impedance load is added, the combined paralleled impedance will prove optimal.
The powersupply will need to be failry clean. Power supply caps take a considerable amount of space.
