My first gen VTF2 amp bit the dust, I'd like to replace the amp. Is there any panel amps that are a direct replacement for that box side, since I paid so much for it would like to keep it. It was used in an apartment and never beat on, the woofer is still in great condition.

I would call HSU first, it might not be too bad pricewise.

+1 their amps are designed for the variable tuning cababilities and built to be used as a system with the driver and box. Trying to use different amps may not work out the best and could be troublesome.

I had to do this about eight months ago, after having the same sub as yours for nearly ten years. I did have the amp sent back to HSU. The repair was about $100, and they repaired more than what was just obviously wrong. It's something to consider.

Yep. I was impressed. It's not something that I expected. But it's nice that the company stood by their product so many years down the road.

HSU won't repair older VTF-2 amps any more. I just got off the phone with them They will try to sell you a different amp, VTF-1 MK2, that has different characteristics and will not fit in the VTF-2 enclosure without modification.

Do you have any local companies that can take a look at the amp and repair it? Otherwise you have a few options:
- Checkout Parts Express for an amp of similar size and specs
- Use an external amp and bypass the internal.

Local repair shops can cost $200-300+ and only guarantee their work for 30-90 days. The difficulty with older amps is that, after the repair on a few parts, other parts may fail. Usually, the repair shop will need the service manual which gives details of the circuit design. I believe that Hsu (along with many other manufacturers) considers their service manual proprietary information.

A few (very lucky) individuals have replaced their electrolytic capacitors (that deteriorate with age and heat) and were able to affect a repair. Many repairs can require replacing parts besides the capacitors.

You can also check out the OAudio amps. I have not had any trouble with either of my PE plate amps.

I also have classic Hsu VTF-2 sub apparently with fried amp.
Dr Hsu says no more support on this older model, he suggests MK2 replacement amp which does not fit in exactly, or a whole new sub.

Did anyone try the MK2 amp rebuild suggested by Hsu?

Have you checked out this alternative?

http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-803

(If the link doesn't work, it's the Dayton Audio Model SPA250 plate amplifier, part number 300-803 available at PartsExpress)

Many reviewers say it's an exact replacement size-wise for the VTF-2's amplifier.

I have the PE SA240-B which is the immediate predecessor to 250. It works fine. I also have the PE 500w BASH amp and will have the 250 (which I purchased on Friday at its sale price) delivered next Tuesday. People in this forum have been quite happy with PE plate amplifiers and their other equipment.

Please post back how long they will last, most plate amp has only one year warranty, which is pathetic and most will die right after warranty period.

If you read through the various threads, very few plate amps from the current (large) set of companies have had issues. Over the years, a few very small companies have failed after they received a bad set of amplifiers.

I have two replacement amps that so far have lasted 5 and 6 years, respectively. One replacement was used on a subwoofer whose amp lasted 11 years. I have six other subwoofers whose plate amps range from 5-20 years old that so far are giving me no problems.

In the late 1980s, I had two standalone subwoofer amps fail for a passive subwoofer. In the early 1990s, I had one subwoofer amp gradually fail (humming louder and louder after three years) that was on a low-level subwoofer (that I gave to a high school kid).
