[Hallicrafters] Cleaning the inside of HT33A amplifier

[Carl]

Coca Cola Zero and Pepsi Max also cleans well. It doesnt have any sugar as 
with the regular versions, its mostly phosphoric acid and carbonated water!

PB Blaster, a penetrant in aerosol cans, sold in auto parts stores, is great 
on tar and stink-weed residue.  Put it on a cotton ball on the end of a 
stick, and SCRUB.

Do this with PLENTY of ventilation.

Follow up with Nevr-Dull cotton wadding chrome polish... again, ise plenty 
of ventilation.
