Original ISKRA carbon film 1W resistor 2.7M ohms
Type UPM100 15mm x 6mm dia (chubby later production)
As used in Marshall, Dumble and Hiwatt amps in the 60s/70s
These are new - old stock from a previously sealed pack
Sold individually
Note that the colour of these is not typical ISKRA. They have a bluish/greenish hue - it is not a bad photo. So if colour matters these may not be for you.
NB I understand that ISKRA 1W resistors were initially made in a 15mm x 5mm package (skinny) which became a 15mm x 6mm package (chubby) in later years. If matching with existing 1W resistors make sure you have the right variant.
