I've owned a second-handed OM-150 for a month and I really like its sounding quality. I'm very interested in Tyxxon's review, especially his recommendation to "change the input and output caps to greater capacitance (15KuF instead of 10KuF) and degree rate because the input resistors located near input caps runs very hot".

Since I'm a real newbie and have little electrical knowledge, I would be grateful if Tyxxon and/or anyone who know gives me detailed instructions and answers to:
- In case I can find only 2 greater caps, is it OK to change 2 caps only? If yes, which ones? please kindly show me, the 2 caps in front part or rear part of the board?
- In case I cannot find any 15KuF caps, can I use each cap 5KuF/80v to wire parallely with each existing 10KuF?

I'm looking forward to your kind instructions. Please kindly send your reply to my email havhoa@gmail.com. Thank you very much in advance.

Strength:

Solidstate amp with tube like sound without lack of bass. For its price is a super bargain.

Weakness:

Difficult to repair. Some parts out of production and AA is out of business :(

I use this amp in my system in dual mono mode around a 1.5 year. Wery powerfull device. In my opinion it has clean, precise sound with warm midrange and accurate bass. I have change the input and output caps to greater capacitance (15KuF instead of 10KuF) and degree rate because the input resistors located near input caps runs very hot. These mods add the depth of sound and bass.

Strength:

Incredibly warm sound for solid state, build quality , looks good too

Weakness:

for price-- nothing

I got one used on line for 575.00 , its great! the sound is so warm but still so precise , it drives my M.L.'s fantastically which is a difficult thing at 4 times that price , to consider anything else for under 1500.00 would be a great way to really waste some money

Strength:

lush, tube-like sound with powerful bass of a good solid state.

I've been using this amp for five years and don't see any reason to spend more money on anything more esoteric. This is a terrific amp. Two detachable power supplies provide dual mono operation. I've used the amp with both Martin-Logan SL-3s and Alon II speakers and it works great with both. A very lush, warm midrange that provides more then a hint of tubes, with a powerful bass.
