Heathkit SB-1000 3-500Z Linear Amplifier
One of the few amplifiers having 160M capability, It is also a popular candidate for 6 and 630M mods. 37 out of 38 reviewers on Eham gave it a 5, a tribute to its excellent overall design. This SB -1000, serial # 00 07 27 89 has the grey panel, and is in excellent cosmetic condition inside and out, as shown in the photos. Overhaul included the usual reforming of filter caps, peaking the input networks, and cleaning and lubing the controls. Additional work included upgrading grid ground connections.
The design is clean and simple. The power out is more than the specs say. I have used it for about 8 years with the original 3-500Z tube with no loss of performance.
I'm limited to an OCF (off center fed dipole) for an antenna. The addition of the SB-1000 made a huge difference in my DX and contesting results.The bottom line is that this is a great amp at very reasonable price. Well having owned this amp for a year now can say its fantastic! I operate 10 thru 160 and this JEWEL handles it all! I have many amps in my time including the FAMOUS ALPHA 86 and its a true beast but lets compare apples to apples! I must say I had and fairly new AL 80A and this is as good if not better than that amp! I do prefer it more than the AL80B which I think is a poor amp! So if you can find one of these grab it and don't let go! The item "Heathkit SB-1000 3-500Z Linear Amplifier" is in sale since Thursday, September 24, 2020.
