Best value Set amp for under $1500 used is ok.

Looking to power some large horn speakers and replace my SS Audio Research upgraded LS10 power amp because it needs service and I am not ready to service this unit for a variety of reasons not worth discussing here.

Specs for the Viking Acoustics L’Instrument speakers

 

are:

Sensitivity: 98 db

Time Alignment: Drivers time-aligned mechanically and electrically.

Bandwidth: 18Hz - 19,000 (18Hz - 50kHz with optional super tweeter)

I have tried 845/805/KT88/120 in non set builds. I’d like to try a 300B or similar set  design for these without burning the budget. I’m based in Australia and prefer to use 240V capable amps.

The LS10 is a preamplifier.

Are you looking for an integrated 300B amplifier?

If so, the Willsenton R300 (mentioned) is the only one, price wise, that comes to mind.

I have seen online pics of some models marked 220V/50Hz on the back.

Here's a recent thread about an owner (R300) updating the coupling caps in one (nice internal pics).

In the US I can have one delivered for $1500 with free shipping (Amazon), but I don't know about availability in Australia (I assume that I would be charged sales tax on the purchase).

Here's something else to look at.

It's a 1 watt preamp/headphone amp/speaker amp that could also be used as a preamp with your ARC.

International voltage with the stock power supply and within budget

I've read about it (online reviews) being used with higher efficiency speakers, but I don't know how they would compare to yours.

This said, I owned an Audion Silver Night DH/SET 300B amp years ago and it was perhaps the most fun I've had in this hobby.

I now use inexpensive (kit) DH/SET 2A3 mono blocks to power vintage wide band single drivers.
