Just about the best turn key Mono blocks you will find for the money.

Rebuild by Robert Silk of Silk Electronics of Slc Utah.

Matched peerless 16309 which is a better sounding transformer.

2 genelex gray jacket kt66 with Raytheon 12au7 black plate. Test 6000 micromhos

2 genelex monarch kt66 with Raytheon 12au7 black plates. Test 6250 and 6500 micromhos on my calibrated Ctech Hickok 539c

Robert also added gold rca inputs.

These have plenty of clean power for their size.

They come as shown with cages.

Condition is as shown. Some scratches and wear but overall pretty clean examples.

I have been using these for a few months. I have been very pleased running my tannoy d7000 speakers.

Please ask any questions before buying. Or contact silk electronics for any other technical questions.

Thanks
