I was mistaken acutually it was tip31 and 32 pair. I found two bipolars connected to those resistors that checked bad and are probably the problem they had heat sinks that were loose. I'll have to order some next time I order parts.

I actually got the thing for the 16" chassis for an 18 watt Marshall copy head I'm building I want to use in my new album but...I just loaned an Ampeg G212 (130 Watts ) to my grandkids for their keyboard practice! Need to get them something smaller to save everyone's hearing! Getting a reading of 6 and 10 ohms on the resistors even though they look barbecued. So I'll sprout for the two resistors two bipolars and a fuse and see what happens.

The Newcomer's Forum / Sears 450G amp

New here hello all.

I have a Sears 450G amp broken that I bought on ebay. I actually bought it for the chassis which I intended to use for a Single ended tube project as it was just the dimensions I was looking for. (and cheaper than a blank had the right front panel setup.

I'm now thinking I may fix for a practice amp this as My smallest SS amp is a Carvin SX200, (for that matter my lowest power amp is a peavey heritage twin  in low power mode) 

(I'm buried in high power amps and no low power which is why I'm working on building an el34 and a SS practice amp built.)

I was wondering if anyone had a schematic or had a Sears 450G as the power amp board has two burnt unrecognizable resistors.  Power transistors are a tip32/32 pair
