Jeff Rowland Model One and Five

My worry is that the two boxed components fail.

Hi

I would think it’s a safe bet for a used Jeff Rowland amp. I wouldn’t worry about it breaking down.  It’s no different than buying a used car, but with much less parts to go wrong. 

Hi ricred1,
unfortunately I don't speak english well to converse on the phone. Anyway, thanks for the advise, it's easier and faster for them.
Thanks!

I've owned several Jeff Rowland components and currently have 735 mono-amps and Corus preamp. Call him and he will answer all of your questions. He provides outstanding customer support. 

Yes, I sent the request on January 30th to the following email address: support@jeffrowlanddesign.zendesk.com, but to date I have not received a response.
I understand that they are very busy, but if they dedicated a section to vintage electronics it would add prestige to the company.
Many thanks jdal.

Here's a Model 1 on Ebay that was updated in 2019
