Celestite, also known as Celestine, is a mineral that forms blue crystals. Celestite is often associated with divine power and is thought to increase understanding, higher consciousness, as well as mindfulness when used in meditation and prayer.
20W FM Amplifier - This Power amplifier is equiped with two Philips bipolar transistors : the BLV10 & BLW87. As lots of FM amplifier design, the RF transistors are in a class C bias. The FM amplifier has a 21 dB gain with a 55 to 65% efficiency. 250mW HF CW Transmitter - Electroinic circuit design…. [from Harry Lythall's website]
Power Amplifier The RF power amplifier stage shown in Figure 5 is based on pentode driver V301 followed by beam power tetrode V302. Here, the plate voltage is set to 250 V and the screen voltage is regulated to 150 V by 5 W Zener diode D306, resulting in a total cathode current of about 30 mA. The 30 – 40 V peak RF signal from driver
A third assembly houses the main power supply. RF CHASSIS -Only three RF stages are employed to pro- duce a full 250 watts carrier at any frequency between 2 -26 Mc., and 200 -225 watts from 26 to 32 Mc. Two type 4 -65 tubes are used as power amplifiers. Provision is made
Behringer BXL900A 1x12" 90W Bass Combo Amp Alum When a stack is too high and a practice amp just doesn't cut it, then this truly affordable wedge-shaped Bass Workstation with a powerful 12" Hard Attack aluminum-cone speaker is exactly right!
Samson's S-amp Stereo Headphone Amplifier is a portable 4-channel headphone amp with volume control for each headphone output, ideal for studio recording.
Jan 31, 2014 · The final tube was a 6146 modulated with push pull 1614's. It had a built-in VFO and Power Supply and weighed 45 lbs. The first versions had cathode keying and used cathode bias on the push-pull modulator. A later update added a power transformer that had bias taps, a keyer circuit to improve CW operation, and fixed negative bias to the modulator.
