6v6 amplifier receiver
Diy Am Transmitter. I am working on a "do it yourself" project. Transmitters are devices that are capable of transmitting audio as radio waves from an audio device. His first post is asking about building the circuit you can find on the internet to build an AM transmitter using a 1MHz crystal oscillator. The transmitter is Bluetooth if you have a modern device such as a smartphone or new generation mp3 player.

6V6 6J5 Class A Vacuum Tube (Valve) Amplifier Circuit
David, aka Grumpy, needs our help. Great news. David is home! It was quite the ordeal to get him home and into the house, but it is done. Thank you to everyone for their support. Now a long road ahead to get him back on his feet and functioning normally. I have started a GoFundMe to help with the medical bills. Please help, if you can.

I can't say, but judging by selling prices on Ebay, the boxes are also sought after. The Pilots are out of my budget, I can only afford Magnavox's. You might consider Eico ST series too.

Messages: 10, Location: Central AR. The one I have is the which I just got cleaned up and will be getting the parts to make it more "up to date" soon.
Things like RCA and speaker connectors, fuse holder and a 3-prong power cord. It still has the original tubes on it, too. I'm sure there are quite a few things I can do but I want to start with the basics. Messages: 3, Location: Hamilton. You won't find much agreement on which sounds better though. The debate goes both ways. The HF will cost significantly more than 2 HF's. I have the power amp sections of the HF's hooked up to a pair of not particularily effiecient or "high end" Paradigm speakers and a Rotel preamp.
There is something just "right" about the sound of this combination.

I'm trying to track down a set of telefunken, amperex, and other hi-fi 6BQ5's to roll in it. Messages: Location: Louisville, KY. Pilot amps, etc.

Simple vacuum tube circuits

The Evolution Series 4T driver employs a "from the ground up" custom designed circuit featuring modern techniques, superior components and much more capable audio tubes. Nevertheless, the electronic features were what Akai pushed forward. Comared to the GX-F71, added to the GX-F91 is a 4-memory auto-tuning so that bias and eq exactly correspond to the actual tape inserted ; the F71 has the function but simplified and with only one memory switch.

Essentially the tube acts like a variable resistance in series with a diode, the cathode to anode "resistance" controlled mostly by the grids. For example, once I connected an output lead from a 15 meter transistor power amplifier to the base of the next stage with a bare wire 4 inches long. The invention of vacuum tubes has produced a new branch of engineering called electronics. This project is a great way to get started in the vacuum tube world due to the low voltage requirements and just how simple it is. First, the tubes were typically dual triodes in one package, so the module had the equivalent of 16 simple tubes. This superb receiver is our most popular regenerative radio. Valley, Jr. The pentode consists of an evacuated glass envelope containing five electrodes in this order: a filament for indirectly heating a cathode, a control grid, a screen grid, a suppressor grid, and a plate.

I, It delivers 50 watts per channel for 8-ohm speakers, and 80 watts per channel for 4-ohm speakers. I upgraded my 2s to 2. The speaker itself in a car serves to amplify sound. I'm always pushing my Ohm walsh speakers because it's a very simple two-way with the tweeter kicking in above the critical mid-range around 8k. I also have a Carver 1.
Instead, use this aluminum, black anodized top plate specifically designed for use as a stereo, push-pull tube integrated or power amplifier using 6V6, , or 6L6 etc. This top plate was punched using CNC machinery with a precision that no hand drilling could ever accomplish. The edges were sheared so there are no 'nibble marks' along the edges. The attractive black anodizing has a slight amount of gloss.

I built this little amplifier back in Since then it has been used in quite a wide variety of locations. For the past few years it has been in my workshop. And sometimes a CD player. That includes the power supply, power amp, preamp, and tone circuits. I assembled the sub-chassis on the bench. The controls, input, and output connections are mounted on the front and rear panels of the chassis.
If the bias on the output tubes ever went to zero for any reason, the tubes would turn on all the way, and this Refer to the circuit diagram also for the bias adjustment points. In a tube circuit that uses fixed bias, the grid-bias voltage is supplied from a power source external to the circuit. Originally the A was designed to run the output tubes very hot, at the physical limit for a tube's plate voltage and current consumption, hence dissipated power.
Great article, thanks!

I apologize, but in my opinion you are wrong. Write to me in PM, we'll talk.
