Presto 87 B

[Mr.Toast]

Hi, new to the site. Just bought a really nice condition Presto 87 B (I think). My research into it has landed me here. My first thought for the amp was to mod it (if needed) to be used as a funky retro guitar amp, but maybe it is more valuable to you lathe trolls?

What would a fair price be for one of these?

Update...this thing sounds GREAT as a guitar amp, not sure I want to know what it might be worth anymore. I plugged it into a Variac and brought it up slowly, plugged my guitar into the input labeled Radio, and PRESTO! Creamy tube tone for days.

These things do make awesome guitar amps. Be careful it's so old those old caps get crappy after a long time and sometimes the transformer will just fry too. All easily serviceable. Also sounds good on a cut disc. It would probably be worth more to someone here though

very cool! does yours have a pair of 2A3's as well?

Tragwag,

I am a complete noob in the lathe world, so forgive me. I assume you are asking if my Presto amp has the associated turntables, and unfortunately it does not. Found it alone, and unloved under a table at a local guitar show. I didn't know what it was, but I knew it was cool. I traded a Rubbermaid storage box full of old untested radio tubes, and $100 for it.

ah gotcha! Yeah I meant the output tubes in the amp itself, mine came with 2A3 tubes which are relatively very expensive!!
