Hi Guys,
As time is drawing near, 307 will have a HLA-150 amplifier from RM of Italy. The makers of the KL amps that Copper sells. I am anxiously waiting for 307's evaluation of this amp as I plan to get one if it is as good as I expect.
Some of you have much more technical brain power than I regarding electronics and schematics.
Therefore, if you get time, I would value your opinion of the HLA-150 amp from www.rmitaly.com.
The web site has excellant pictures and online schematics that can be viewed in pdf format.
By what I saw, I think this will be my next amp. All mode and all frequency with 11 meter capability without modification, not to mention highly filtered and swr protection.
If you get a chance, please have a look at it as I would value ANYONES opinion to aid me in an educated decision to buy it or not.
Thanks,
Kattracker |

It looks like a good little amplifier, and probably with a good price. But I also see its a low drive amp, so what is it really good for except behind a cb radio. Most HF rigs would do almost as much as this amp, and most put out way too much power to run into this amp. Even a 2510 might over drive it on sideband, it gives a 20 watt max drive. For CB use, I believe you could get a lot more watts for your money with other amplifiers. And as for as running clean, I think amplifiers get blamed for operator's errors most of the time anyway. That's just one old CB'er's opinion.

Kattracker,
I'm not sure I'm any more technically inclined when it comes to electronics than you, but I was able to look at this amp and it indeed does look impressive. The filtering got my attention as did you. It's hard to find amps in this price range with any internal filters to reduce harmonics. An amp covering the bands like this sure does look impressive if it works as well as it looks. I'm sure 307 will look into that.
Based on my own experiences with th RM line of amps, they are not the most powerful, but sound extremely clean in all modes. No doubt this one will also.
If I had the bucks to drop on a new amp, yes I would sure look at this myself. If you plan on expanding into the HF ham bands someday, could be a great choice. On the other hand, with it's filters, it sounds to already be a good choice for those that care about how clean their signal is going out.
Looks pretty nice to me.

Kattracker for the money per watt look at the texas star amps, there really great smaller amps for the money. Its a easy mod to change from CW Transmitter to a regular amp. For the money. Like scrapiron most amps are dirty due to being over driven by a over modulated radio my opinion. |

Good point on the overdriving.
I have variable output on my Lincoln so never considered that a problem.
I have seen these amps sell for under $300.00
I am going to consider the KL500 and also the Texas star. I had a Texas Star 350 in 1991 and it was a good amp. I am running a Palomar 250 now and it is okay but I prefer something else.
What is the conversion procedure for a Texas Star?
Sorry about the bouncing around on subjects on this post, but I was expanding on Scrapiron63, Alsworld and Crafters reply in one post.
Thanks,

This looks to me like rm's first of possibly many offerings of broad band amps,I bet if this one sells well they will offer many larger units both low drive and high drive and from a highly respected name no-less 'cause that's what we need more quality and less suspect junk(like the ones that have universal labels)sometimes you get a good one and sometimes you don't. |

Scrapiron,
That amp would be PERFECT for use with Icom's or Yeasu's low power multi-banders like the new IC 703 or the FT-817.
Now, if only the amp could cover 6 meters as well. |

Scrapiron has some excellent points there. Most of the new HF rigs of today are using a pair of 2879s and can easily do 300 watts when reworked.
If you hold a General Ham ticket, then as Scrapiron says, this amp is a good choice but why not go with a HF rig? Your Lincoln only covers 10 and 11 meters. And using this amp would be a waste if it was only used on A-M in the 11 meter band. Copper has many other amps that could eat this one alive if you're limited to 11 meters. And cheaper too.
Just my opinion Kat.
