Good summary of the pros and cons. I have an Acom 1010 and have been very happy with the performance. Tuning/matching is a breeze and the protection circuits provide peace of mind in case of operator error/overexcitement chasing a DX station. The design and finish of the unit is first class and the small size and low noise means that it can sit on the radio desk next to the transceiver. My only niggle with the unit is that it has to be powered up to switch antennas. It would be interesting to hear your thoughts on the availability of replacement valves. Y

Great video as always Peter. I have had the ACOM 1000 (1kw amp) for 2 years. The reason I got this model (tube/valve) is that it can run a full kw on digital modes (in fact this was ACOM factory recommend because I run a lot of ft4/8) transistor amps have to be derated by50% an extra 500 watts over the 1010 in ft8 is substantial

thanks for your videos. as far as here in the USA, conventional wisdom says that one's first amplifier should be a legal limit (1500 watts USA) amp. then, have a backup amp of 700 to 800 watts.

I always fancied driving a valve linear to 200-250w on CW. Normally i run 50w. That would give me an S point advantage and reduce the heat load on the radio especially on the occasional days i take part in contests. Things got a bit toasty last weekend especially as it was a hot day.

Excellent video Peter. Assuming the Ofcom 1KW proposal goes through later this year or early next year, do you think that demand for higher power (700W - 1.5 KW) linears in the UK will be able to keep up with demand? Also do you think there will be an increased number of second hand "modest" power linear amps on the market (thinking the smaller Ameritrons and the 250/300W solid states such as the RM models) as people trade up from their current set ups?

If you double your power from 1Kw that is 3db or 1s unit going from 700w to 1K there will be not much increase in signal.

Hi Peter, Very informative and interesting video. I wish I’d seen this before I bought my amplifier. I purchased the Acom A700 which interfaces nicely with my FTDX101. I am still using an 66ft EFHW at the moment. I built my own high power 49:1 UnUn with 3 x FT240 43 toroids stacked. I added you loading coil extension kit so I could tune the EFHW on 80 metres. According to my Antenna Analyzer SWR on all bands (apart from 60m and 30m) is below 2. To be safe I also have an LDG at600ProII between the antenna and A700. I am experiencing problems using the A700 if I drive it with much more than 10 watts from the exciter which gives me around 300 watts Peak power. If I try to increase the power past that point or get too near to the microphone; the A700 reverts to standby and shows a fault indicating ‘Excessive PAM current’. I’m Wondering if the LDG just can’t achieve a good enough match although my SWR bridge indicates it has. Wonder if you have any guidance?

I know exactly what you are saying. I purchased the A1200s and had the same issues. Peter was absolutley right that the valve amp protects your sanity. I almost lost mine with the A1200s and finally decided to go for Acoms A2000. The only thing that Peter should have mentioned is that the valve is the GU74B a Russia tube equivakent to the one Peter mentioned and that the only bitter pill in buying a valve amplifier is that it is wise to buy an extra tube just in case. This could throw you back around 500 euros nowadays due to low stock levels, though the Chinese have come out with an equivalent costing the same but at least removing scarceity out of the equation. With regards to the durability of this Chinese valve only time will tell.

I have an rf kit rf2k-s solid state amp that has a built in tuner and instant band switching. Critically it has no warm up time, just time to boot the raspberry pi that controls it. It has 2 ldmos run way under spec so is capable of around 1800w constantly with very quiet cooling.

I am afraid it is very unlikely. The big attraction of a tube amplifier is its versatility in matching. Broad band tuning network would probably add a lot to the cost and reduce the life if the tubes significantly.
