Proco Rat build

[Catmandue]

Cool build , here's my old war horse! I think it's a pretty early version. Probably needs new Electros + but sounds fine

I've read if one has reverse threads on adjacent screw heads they sound better or sumptin like that, I don't know?

Very nice! Looks like it should be in a gear museum.

Rats sound very good through Marshalls.

Looks exactly like my source!

Cool. Appears to be one of the first commercial units with the sheet metal enclosure & the L shaped removable top panel. Produced from '79 until the change to the later enclosure type in '83, or so I've read. Cheers

I require quality poop! I need good noise!

Fenders as well Bro!

Totally agreed! You're preachin' to the choir my brother! Fender tube amps are delightfully special.

Fuk Photobucket, time to load everything I have there onto a flash drive. Are there any other places like photobucket used to be?

 

[Catmandue]

I finally figured out how to get images on here with imgur. Some of you guys were tripping on that post I did earlier. Photobucket has turned to poop.

Let's hope that Imgur doesn't follow in Photobuckets slippers.

So, I've never owned a Rat...

Recently, BYOC started stocking their Mouse kits again. , and today I assembled it together. The BYOC-supplied LM308 transistor is installed. Didn't have time to plug it in, but the "on" light and the clipping LEDs come on. Since I also have a vintage Motorola LM308 (Thanks, Ivan!), I want to install that one and compare between the two transistors. So... Is it as easy as slipping one of the leads into the 8-dip socket one at a time, and follow this datasheet's pin diagram from the TO-99 can-style to the rectangular 8-dip socket?

Since this thread, i bought a clone with an LM308. I already took the cowards way out.

I did similar recently; looking through that excellent treble booster thread I went online to order a kit then just bought one ready made instead... I hate soldering.

Hey Ivan you finish that Proco Rat build ??? I thought maybe youd want to send it to me for evaluation hahahahahha. ,)

Very very nice work ivan H.

Be interesting to here the results of the comparison between DIP chip type LM308 & the TO-99 (metal can) type Motorola LM308. From what I've read on stompbox forums, the TO-99 type was only used on the first few prototype ProCo Rat's. People swap out their DIP (dual inline pins) type LM308 for the TO-99 type as a supposed upgrade, though whether there's any noticeable difference I couldn't say.

I've been using it for 3 yrs, it's a permanent fixture on my board. I could, when time allows, possibly throw another together for your evaluation. Cheers

Today, I could only get about 5 minutes of playtime with the Mouse..........

I can't make a fair assessment after just a very few minutes, but it sounds good right from the start played thru a clean Spiffy XVI amp. The Tone/Filter control reduces the highs by adjusting it clockwise. Plenty amounts of volume boost through a clean amp. Lots of crisp and tight distortion with the distortion control only halfway! We'll see what tomorrow brings...
