Nov 16, 2015. National Semiconductor has been fast at work designing analog products for the high-end audiophile market. As fortune would have it, these products such as the LM4780 Power Amplifier Chip and the LM4702 Driver Chip (are easy to implement into high-quality designs. National Semiconductor introduced the LM4702 integrated circuit in about August 2005. The official news release was on 19th September 2006, heralding it as the first member of a new family of high performance audio amplifiers. In 2007 the new family grew to include the LME49810 (200V Audio Power Amplifier Driver.

The OM purchased his unit about 4 years ago and overhauled it, including a pair of new Russian tubes. The unit was used on a regular basis until the OM passed. The amp has not been powered for about 1.5 years.

The family has decided to lower the price to $700 or offer. Local pickup in Lancaster, CA or shipping may be arranged. Mtk Flash Tool Torrent Download. Email: **Please To send an email** 2017-12-15 HF Amplifiers Here is a very nice Drake L-7 amplifier for sale or trade. It is in good condition except for the original Eimac 3-500 tubes might be a little soft.

Output is around 800-900 watts. The power supply has been upgraded with the Heathkit Shop PCB/cap kit and the RF deck has been gone over and caps replaced.

The sale includes an Ameritron ICP 240 Inrush protection outlet that also serves as the on/off switch for the amp. The amp looks good and works great on all bands 10-160. I'd consider a SWAP for a late model ALS 600 or an Icom 7300, or sell for $1000. No shipping on this amp, but can be picked up here or I will meet within a reasonable distance.

I have one new RF Parts 3-500 tube I will include with the sale. I have more pics I can send.

I can't get any pics to load on this site. MAKE ME AN OFFER.

This amp is excellent! Non Smoking Home. It has the 10 meter mod as well as a couple more. I have run this amp on 160, 80, 40, 30, 20, 17, 15, 12 and 10 meters. It's a solid performer. It runs nice and cool even when the output is 1400 to 1500 watts for long periods of time.

All of the lights have been replaced with white LEDs. The cabinet is an 8 or 9 out of 10, operation is definitely a 10 on a scale of 1 to 10. It's very clean inside as well. The TL-922a is a solid performer and beautifully built. It's currently in use so if you'd like to come over and tune it up I'd love to show it to you.

Prefer not to ship but if you'll pay the freight I'll have it professionally packed and shipped to your location, even internationally. If you're with 150 miles or so of extreme Northern Virginia, Harper's Ferry WV, Frederick, MD or Gettysburg, PA I can meet you half way depending on distance.
